1/31/26 Report - Tips for Identifying and Dating Targets. Case Study. Remote Viewing Techniques for Target ID.

 

Written by the Treasureguide for the exclusive use of the Treasure Beaches Report.


Surf Chart from SurfGuru.com.

Later Saturday we might see something start to develop again.  

This morning there is a small lazy surf and a high tide.  The low tide will be around noon.

---

Not too long ago I posted a fragment of what appeared to be a gold and diamond something or other, and the person who found it naturally wanted to know if it was old.  That was made more difficult by not knowing exactly what kind of object it was.  We were missing a lot of information that could have been helpful to better identify the object and its age.  First, like with many such requests, the submission was lacking basic dimensions, and there was nothing in the photo for size comparison.  That information could of been helpful.

Second, the item evidently hadn't been tested for gold content.  We don't know for sure that it was gold. That information could have been helpful too.  Modern gold is often 9, 10, 14 or 18K, although there are exceptions and some countries use more high purity gold, such as India and China.  And there are various types of plating too.  Deletion gilding is not uncommon on Spanish Colonial items from South America.  Some forms of electroplating are more modern, but gilding is an old process.  It gets complicated, but all that kind of information can help determine the source or age of an item.  

A third important thing is context.  Where was the item found?  Was it found with other items or coins that can be dated?  Was it found in area where shipwreck items have been found in the past or where some other historic event took place?  

All of these things can add to the picture.  Any one piece of information by itself probably will not determine if an item is old or not, but if you put together the whole picture you can get a better idea.

Many items have been used over the centuries without much or any change, such as simple gold or silver bands.  Claddagh rings have been used for centuries and are still being made.  Crucifixes have been used for centuries, although there are some diagnostic features or forms that might help determine the source or date range.  Many styles have lasted centuries.  

It is often difficult to determine the source or date of an item, especially from a photo.  Things can end up in strange places.  A 2020 coin can get dropped on an old shipwreck site.  Items from different dates and even shipwrecks can get intermingled.  

There can be all kinds misleading clues and tricky questions involved with determining the source or date of a mystery item and that is why it helps immensely to have all the information possible, including the things I mentioned above when submitting a mystery item to be solved.  Help us help you by providing as much information as possible, even if the information might seem obvious or unimportant to you.

If you submit a mystery item, don't be afraid to submit more information or something more you learned after the initial post.  If you were motivated to have the item tested, for example, let us know what you learned.

Sometimes it takes years to learn about an item.  I've found things that I only figured out after several years went by.  

As an example, for years I thought the item shown below was probably a finial.  It is hollow on the right end and looks like it might fit onto something.




You can't tell from the photo alone, but the material is lead and it is less than two inches long.  And the context, which you'd have no way of knowing unless I told you, was from canon emplacement on an island where there were battles during the 1700 and 1800s, which was evidenced by many artifacts of the era such as musket balls, grape shot, military buttons etc.  Furthermore, it was dug just a few feet from where there was a cannon.  In retrospect, I wonder why I didn't recognize the item as soldier art much earlier?  

The mussel of the artifact is shaped very much like that of the cannon from the island and the item shares many of the same features as the actual cannon. Below is a picture of the real cannon.  Compare the muzzle on miniature shown above.  


The actual cannon also has rings around the barrel, very like the carving.


Even though the miniature is not an exact replica, I am now pretty confident that some soldier with some lead, maybe a musket ball or two, decided to spend some idle time making a little cannon.  It took me years to come to that conclusion, I think partly because soldier art just wasn't something that I paid much attention to in the past and the miniature is much more decorative than the actual cannon. 

A reader of this blog suggested that it might be soldier art.  I am thankful for that and now feel highly confident that is what it is. Considering ALL the evidence and matching the artifact to an actual a cannon from the site, seems to make it all fit.  The lead would be available and easily formed, and a model was right in front of the bored soldier.

Beside size, material and context, the form of the object is important.  It can be functional and serve a purpose, or symbolic or decorative.  I was trying to match the lead object to something functional and decorative - a finial, but it turns out, that it was more art and recreation.  I was very fortunate to be able to match it to an item of similar form from seemingly the same location and time period.

Don't be too eager to accept the first answer you get as the end of the matter.  Keep studying.  Keep learning.  What you learn from the process can be enriching and provide valuable information that you will find helpful far into the future.

Report whatever you know about the size, material, context (history of the area and similar find), and form.  Pictures are two dimensional and don't show everything.  Any of that information can help fill out the picture and help you come to a conclusion.

---

Start with a quiet time and place.  Maybe before bed or just after awakening. I feel meditation is more productive in the morning because you will be rested and awake.

Focus yourself on why you are there and what you intend to do.

Slow down your thinking and try to deeply relax. But keep your mental focus.

Many people use slow deep breathing to relax.  

Be open to random thoughts but don't try to think about anything.  Just let the thoughts go.

Place the artifact in front of you or hold it in your hand.

Record impressions.  Don't judge or evaluate at this time.

Write or sketch whatever thoughts or visions come you.   Don't write much - just one or two words at a time.  Be more in the visual realm than verbal.

Those are pretty much the steps involved with remote viewing, just adapted to target identification.  I view it as basically a type of limited brainstorming.  Be open to ideas and feelings and perhaps something will strike a chord.  It is supposed to help thinking outside the box.

Give it a try if you are so inclined.

Here it goes again.  I'm preparing another obituary for a newly deceased 98-year-old relative.

1/30/26 Report - Target ID: Experiences, Impressions, Techniques and Tips. Wind Erosion and Eye-Balling.

 

Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


There has been a lot to report the past couple of days, and I know I didn't get to all of it. I tried to present what I thought would be of most immediate help. Today I'll get to some other types of issues.

DJ conducted an experiment to see what he could tell about a buried object from the Manticore's 2D ID display. Here is how he described it.


It had been months since I used the Manticore and found an iron target that seemed bigger. Hoping it was spikes (like even iron spikes), I worked the coil tip around and realized it seemed square. I drew the lines in the sand as a test then realizing it was not spikes dug it up out of curiosity.

It was only a modern door hinge but what struck me was how the detector traced the shape.


Outline of Buried Object as Determined by DJ from
the Manticore Target ID Display.

Below is the same object after DJ uncovered it.

Object Still in Ground (Left) and Dug Up (Right)

DJ was impressed by Manticore's ability provide information about the shape of the buried object. I agree. In fact, before getting DJ's email, I was planning on mentioned my own observation. The last time I went hunting, I was impressed by seeing a very good image of a lead jig head on the Manticore's display before digging. The outline of the object as shown on the display was remarkably accurate. I was really amazed.

Of course, there is a knack to using the Manticore to get the most accurate target ID, and even then the display image won't always be that perfect. I mentioned before that on the display screen a gold band looks very much like a coin. For one thing, the display image of a ring does not show an open loop. It shows something very similar to a coin. But still, I think it is pretty amazing.

To get the best input for the 2D ID map, you'll want to sweep multiple short sweeps over the target and vary the direction of the sweep. Below is what the Manticore manual says about producing a more accurate target trace. I just consulted the manual after typing the above.




Below is the ID map as shown in the Nabticore manual.



I learned the same thing in the field through experiment and experience, but I used more sweep angles than two.

During that hunt, I found an area with many small iron objects and many larger iron targets at at other areas of the beach. They were all easily identified as iron from the readout, but I dug a good many of them just to double check.

There were also a lot of small copper bits on the same beach. They showed on the Id screen very much like foil, except a bit higher on the conductivity scale. Both foil and thin copper pieces showed up on the center line, but foil was more to the left (lower conductivity). An old nickel showed up as a 25.

Another thing I noticed was that I often heard a little blip even when the coil did not go over the target. That was when the target was a little outside the diameter of the coil, maybe an inch or so. Those signals were not as strong or solid as when the coil actually passed over the target. They were just little blips. I had coils in the past that would detect out a short ways from the edge of the coil, so that was not totally new to me. It is actually useful to know that because if you get a very small blip of a signal as your walking along swinging, you might want to check back and see if it was something good that you just missed getting under the coil by a very small amount. That is how it seemed to me from a few casual instances in the field, but I'll have to investigate that more thoroughly in the future. Maybe someone can verify that observation.

To sum up this section on target ID, I still say that if you want to make sure not to miss everything, dig everything, however if you lack time, patience, or maybe physical energy, this target ID stuff is very helpful.

The following report is from Mark G.

I had to get out tonight [Tues.] after work see how long I could last in the cold. Turns out it’s not the cold but the wind that cuts right through you. Went to the next beach on my list and was surprised to see a cut on the beach with steep walls. If the surf keeps up tomorrow it should dig deeper into the high beach. I tried the cut, tide was high and sand was soft, no hits timing was off there. I originally wanted to dry sand anyway so I went back up to beach which is much smaller than the last time I was there. Just started to swing when a golden glint hit my eye, I looked down and there lying on top of the sand is the Eiffel Tower (swung my coil over it just to make sure). My next target was an earring, it was smaller so I did find it with the detector but it was lying right on top. I started taking pictures as proof of wind erosion, see attached. I have seen this before, I have found a ring completely lying on surface last winter. Just like with a good storm and high surf moving sand, the conditions also have to be right for wind erosion to really move sand, timing is everything. Right now and maybe more tomorrow if the wind keeps up you can see the sand piling up in the dunes and entryways. I’ve seen it before during the dry times in winter right at the edge of high tide wetted sand the dry sand is picked up by the wind off the ocean and the shells and heavy debris is left behind. I would have to say that the wind today moved inches of sand from the waters edge of the beach into the dunes just to expose my first target, the Eiffel Tower. Might be a good time to hunt Emeralds on the beach mid Island.

Here are the items Mark eye-balled.



I've done several posts on eye-balling and once did an article for Lost Treasure Magazine on the subject. It is something I enjoy and find helpful.

Here is an old post about eye-balling after a strong wind.


===


EXTREME COLD WATCH IN EFFECT FROM SATURDAY EVENING THROUGH SUNDAY AFTERNOON... ...FREEZE WATCH IN EFFECT FROM SATURDAY EVENING THROUGH SUNDAY AFTERNOON
Instruction: Dress in layers including a hat, face mask, and gloves if you must go outside. Keep pets indoors to protect them from the cold. Make frequent checks on older family, friends, and neighbors. Ensure portable heaters are used correctly. Do not use generators or grills inside. To prevent water pipes from freezing; wrap or drain or allow them to drip slowly. Take steps now to protect tender plants from the cold.
Description: * WHAT...For the Extreme Cold Watch, dangerously cold wind chills as low as 7 degrees possible. For the Freeze Watch, a hard freeze with temperatures as low as 20 degrees possible. * WHERE...All counties in east central Florida. * WHEN...From Saturday evening through Sunday afternoon. * IMPACTS...Dangerously cold wind chills could lead to frostbite and hypothermia, even with limited exposure. Freeze conditions will likely kill crops, other sensitive vegetation and possibly damage unprotected outdoor plumbing. * ADDITIONAL DETAILS...Strong gusty winds are forecast on Saturday, reaching 35 to 45 mph or higher at times in the afternoon and evening. Preparations for the very cold temperatures should be complete by Saturday morning.

1/29/26 Report - Treasure Coast Beach Conditions with Photos and Reports. A New Front to Come Trough Soon.


Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


Walton Rocks Tuesday by Joe D.
  

I'll start out with beach photos from Tuesday and below present Wednesday photos. That will allow you to see how some of the beaches changed in the past day.

Joe D. took the Tuesday photos.  Below is Joe's report.

   The ring i found yesterday here in Melbourne; it's Sterling. Today we drove all the way to Walton Rocks and worked our way all the way back to Melbourne! Only detected at John Brooks,  and the huge cut at South Jettty Park, as they were shoring up the sand where its about to erode the roadways there! Tons of signals and junk, but we only managed a few very crusty coins there with our dueling Manticore's!😆 Erosion and cuts got progressively smaller as we went back North! Always interesting to see how different the beaches are, as you travel some distance! Ft.Pierce definitely cought the majority of erosion! The jetty cam doesn't do it justice!🤯 Hopefully more good detecting ahead with the lovely weather.

Below are more of Joe's pictures.


John Brooks Tuesday by Joe D.

It looks like the Wednesday cut at John Brook was smaller than Tuesday, for example.

I went out this morning (Wed.) and did a little hunting. Below is what I saw.


John Brooks Wed. Morning.


There was a cut a Brooks, but from the previous photos submitted by readers, it looked like the cuts here were not as good.  They are smaller.  The sand at the top of the slope in front of the cuts was mushy.  Targets were very scarce there.

John Brooks Wednesday Morning

Again, the cut is diminished.


Frederck Douglass Beach Wednesday Morning.


Walton Rocks Wednesday Morning.


 The photo above doesn't show it, but there were some very small cuts to the north and below the small cuts were some dips that held a good number of targets, some good but with a LOT of junk.  

There was older orange sand just below the surface and some shell layers below that.  I spent some time picking through the junk.

At the southern end of that area was a lot of small iron - some of it splinter small.  A little farther in was lead and little bits of copper.  But there were some crusty green coins in between.

Looking South at Walton Rocks.


There were some decent sounding deep targets down there.  I regretfully left some of them because of the depth and underlying rocks.


Example of Partially Exposed Rock.

There weren't as many exposed rocks here as there was the last time I was there.  The rock shown above is about three or four feet long.

Surf Chart from SurfGuru.com.

Looks like the surf will be from the east until the next front arrives.  

You can see the wind shift just before the surf increases.  That has been the usual pattern with these fronts.  

The cuts have been starting before the surf peaks.  The wind cycle is quick.  You see the cuts and then the wind surf direction changes and the filling starts again.

It will be good if we get some more erosion before the present erosion completely disappears.

1/28/26 Report - Beach Photos and Reports from Around the Treasure Coast. Some Nice Cuts.

 

Written by the Treasureguide for the exclusive use of the Treasure Beaches Report.


Turtle Trail Monday by DJ.


Above you see Turtle Trail as it looked Monday.  DJ took the above photos to serve as a base line for comparison Tuesday after the front came though.  Below are the photos of Turtle Trail, taken by DJ around low tide at 8:30 AM.


Turtle Trail 8:30 AM Tue.

Turtle Trail 8:30 AM Tue.


Turtle Trail 8:30 AM Tue.

You can see the changes for yourself.  Below is how DJ described it.

About a 4-5 foot cut ran both directions as far as I could see. It was in dumped sand. Not many targets but lots of larger and older shells and rocks like we used to see.

What does not show is how low the beachfront at the swash is. When I stood there my head was below the upper landscaped dune.

DJ then went on to Seagrape.

After scouting Turtle Trail thought I would go north to see if the cut ran closer to the dunes. Stopped at Seagrape and saw more shells and rocks. And some shell piles with heavy shells.

Found a tent peg (rang up high), some modern coins that had been there a while, a .22 bullet, the lip from an old large conch shell and some of the largest iron flakes I have seen.

Also found a rock shaped conglomerate that rang middle tones and a little iron. The rock is kind of unusual and has metal imbedded in it so it’s not really a rock but can’t tell what it is.

I’ll try to crack it open and let you know.
Conditions sure seem better and if we get another front before the east wind who knows?
Regards
DJ

Below are those pictures from DJ.

Fort Pierce South Jetty Beach Cam Tues. Around 3:30 PM
South Beach Zoom View.

This cut developed since Monday.  Turtle Trail was also cut Tuesday morning.  Al C. sent the following photos of John Brooks from about 8:30 AM Tuesday


John Brooks from About 8:30 AM Tuesay by Al C.



Thanks to AL C. and DJ for the great beach photos.

So there are three or four beaches that developed cuts after the front came through.

I'm pretty confident that some old shipwreck items will be found.  If you recall my old beach conditiosn rating scale, I'd give current beach conditions a good three and maybe more.  Not only are there some nice cuts, but the beach front is low and there are shells and rocks - all good signs.

Notice once again, how some of the beaches are correlated.  

I feel like I'm forgetting something, but I'll go ahead and get this posted and maybe be back later.

Good hunting,

1/27/26 Report - Erosion Now! Too Many Coins? Silver Coins of Another Sort. Coins To Catch with a Magnet. Maybe it Wasn't Columbus.



Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.

John Brooks Beach About 10 AM Today (Tuesday)



Thanks to Al C. for this current photo.

A number of mints around the world are “minting” profits by striking a huge variety of coins for collectors instead of for circulation. For example, the Royal Canadian Mint strikes over 300 different coins each year, with only a handful of issues for circulation purposes.

The governments of a number of less affluent nations have been able to raise revenues by collecting royalties from authorizing issues of non-circulating legal tender (NCLT) coins that were then marketed primarily to American collectors. Examples of such countries were (and in some instances still are) the Cook Islands, the Isle of Man, Liberia, the Marshall Islands, Niue, and several Caribbean nations.

In most instances, marketers promoted a coin issue, then found a cooperative government and mint to authorize and strike the pieces...

Collectors have limited budgets, some modest and some enormous. While there are a number of collectors of the annual uncirculated bullion issue, even that is becoming a challenge with today’s record high levels of silver prices. Even fewer collectors have the budget to try to accumulate all the different varieties of uncirculated and proof Silver Eagles.

While it is understandable that U.S. Mint officials have an interest in maximizing revenues and profits while working within Congressional constraints, is it possible that the market is becoming so saturated with varieties of Silver Eagles and special editions of other coinage that it will diminish future collector interest?

Here is the link for the rest of the article.

If you've been metal detecting in Florida very long, you've probably picked up quite a few Canadian coins. Just a reminder to check your Canadian coins for silver.

Here are some to look for.

Five-Cent Piece: Minted from 1858 to 1919, it was made of 92.5% silver.Dime: Minted from 1858 to 1919, it was also made of 92.5% silver.
Quarter: Minted from 1870 to 1919, it was made of 92.5% silver.
Half Dollar: Minted from 1870 to 1919, it was made of 92.5% silver.
Five-Cent Piece (1920-1921): Transitioned to 80% silver.
Dime (1920-1967): Transitioned to 80% silver.
Quarter (1920-1967): Transitioned to 80% silver.
10-Cent Coin: Minted from 1920 to 167.  Made of 80% silver.

I once did a post on using a magnet to separate coins.  Many of the modern Canadian coins will stick to a magnet.  You can quickly find the silver because they will be left behind after removing the magnetic ones. 

A magnet can be used to help to pick out other kinds of coins.  For example, if you have a pile of one cent coins, a magnet will quicky pick out the steel war cents.

A magnet will catch a lot of foreign coin too. A lot of German coins, for example, and many Canadian coins minted after 2000, the 1 and 2 pence UK coins struck after 1992, and the Swiss 5 centime coins are some other examples.

There are also rare planchet errors that will stick to a magnet too.

Be careful with the magnet though. A strong magnetic attraction can leave a mark on a coin. In my old post I suggested some ways of avoiding that damage.


Are you passing up those magnetic coins with your metal detector?  Good chance.

In their theory, sexually transmitted syphilis emerged in South-Western Asia about 3000 BC.

A more popular theory suggests that those travelling with Christopher Columbus brought the disease from the Americas to Europe in 1493...

The pair penned a commentary on the new research, published alongside it in the journal.

"The finding points to an origin for syphilis in the Americas rather than in Europe," they said...

Here is the link for more about that.

1/26/26 Report - Coins Pumped Up in Dredged Sand. Consideration on Mystery Item. Cargo of Manila Galleons. Evil AI.

 

Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


Sifter for Replenishment Project at Dollman
Photographed and submitted by Mark G.

The sifter sifts dredged materials to 0.24 inches.

Speaking of dredged materials...



October 20, 1957, at 4 a.m. was the incredible moment that the giant dredger dug out the last sand dune and cut the island in two...

Bill Rapp, a Port Mansfield resident, was there for that moment and was elated that he was. He wrote: “You often dream of things and they come to pass...

In the dredging that continued one bright sunny afternoon, the mud and clay being sucked from the channel and spewed onto the banks suddenly brightened as silver coins began sparkling in the sunlight... The dredge had crushed an old Spanish Galleon, the classic sailing ship, buried there for four centuries. Work was stopped for a while and the coins collected...

The ship that was discovered there was the Santa Maria de Yciar, one of four ill-fated ships carrying treasure that had set sail together from Vera Cruz, Mexico, in late April of 1544 on the way back to Spain... Estimates are that the ships carried the equivalent of about $80 million in today’s purchasing power.

The three wrecked ships... all sat undiscovered for four centuries. The Esteban and Espiritu Santo were both found years later a few miles north of the Mansfield cut. Treasure hunters descended on them and had collected quite a fortune when the State of Texas took action.

Here is the link for the entire article.

The Port Mansfield Cut and the treasure discovered there | Texas Standard


The coins dredged from that cut were of the Carlos and Joanna type shown below.

Texas National Park Service Photo.

You might recall some very similar coins found on the Treasure Coast that I posted in this blog.  Some of those came from a mid-1500s wreck site.

Treasure Coast hunters talk a lot about 1715 Fleet treasures, but there are other shipwrecks along the Treasure Coast, both older and newer.  Not all shipwreck finds, not even Spanish shipwreck finds, are from the 1715 Fleet.

---

Concerning the mystery item that I discussed yesterday, Warren D., who found an old diamond and gemstone ring himself, added the following comments.  


Another thing to consider when analyzing 1715 fleet artifacts, jewelry, etc.

I was told by Bob Marx that my ring was Oriental workmanship. Oriental techniques may/probably vary from European/Georgian techniques in the same time period. I think most information on the internet addresses the European techniques in that time period.

I researched theses done by Prof. Edward R. Slack of Eastern Washington University to try to understand the Asian influence on Spanish colonial culture. Asians migrated to colonial New Spain and established shops like the El Parian in Mexico City, opposite the Viceroy's home and Mexico City mint. Asians included India citizen, famous for precious stone cutting and polishing, think of the "maharajah" jewels...


Thanks Warren.

On a related note...

1/25/26 Report - Famous Remote Viewers of All-Time. Exploring a Mystery Item Find from the Treasure Coast. Cold Front Coming.

 

Written by the TreasureGuide for the exclusive use of the Treasure Beaches Report.


Two Views of Mystery Item found by Dan K.

Yesterday I posted this mystery item found by Dan K.  It is gold color and has a lot small clear stones set close together.  The second view shows the items as if the item was flipped over top to bottom.

This isn't an easy one, for sure.  It is complex and irregular in shape.  Obviously broken and a lot of it missing.

I should have asked for a size dimension.  You'd guess not too large.  Size, composition and any detail might help with identification.  Try to be as detailed as possible when submitting mystery items.

I suggested that Dan have the item tested for the gold content, perhaps taking it to a pawn or jeweler that will use XRF.

Mark G. submitted the photo with query to Copilot.  Here is what he got.


Your Fragment: What It Suggests

Based on your description and the image:

•             Crude goldwork: Pitting, casting flaws, and uneven bezels are typical of 1600s–1700s Spanish colonial jewelry.

•             Square diamonds of varying size: Strong match for table-cut or senailles (irregular chips), often used in religious or decorative fleet pieces.

•             Possible hinge or mechanical feature: Could indicate a pendant, locket, or rosary component—many fleet finds include hinged devotional items.

Gold alloy with high copper content

Fleet-era Spanish gold was often:

•             22k–24k for high-value items (very little corrosion)

•             But lower-purity gold (e.g., 18k or less) was used in trade jewelry, devotional items, and lower-tier gifts

These lower-purity alloys could contain:

•             Copper (for hardness and cost reduction)

•             Silver (sometimes, but less reactive)

Over centuries in saltwater, copper oxidizes into:

•             Greenish corrosion (cupric chloride or carbonate)

•             Verdigris-like buildup, especially in crevices and around stones

This matches what you’re seeing: green crust on the diamonds and gold

Copper component adjacent to gold

Another possibility is that the fragment includes:

•             A hinge, pin, or mechanical part made of copper or bronzeMy

•             These were often used in lockets, pendants, or rosary boxes

Copper was easier to work for moving parts, and it was often paired with gold in colonial jewelry. If the hinge or structural element was copper, it would corrode and spread green oxidation to nearby gold and stones.


Right or wrong, copilot offers a lot to consider, but I'm not so sure about any of the first bullet point.  To begin with, the stones seem to be in what I would call a channel setting instead of a bezel.

Close-up of Mystery Item Setting.

"Senaillies" typically refers to a simplified rose cut.  I'm not certain, but this seems more like an antiqe sqauare cut to me, but I'm no expert on diamonds. 

 

But maybe, according to the following defiinition.

Senailles are type of simplified rose cut diamondoften referred to as small diamond chip with few polished facets. They are commonly used in jewelry, particularly in the Belle Époque period, where they are often paired with larger diamonds. Senailles are typically set in closed settings and can be found in various styles, including pendant designs and rings, showcasing their versatility in antique and vintage jewelry.  (Source: Antiques Report.)


Below you can see the difference between the rose cut and other more modern cuts, such as the brilliant cut, which is very common today.



Unfortunately, I can't see the bottom of the diamonds, but due to the open back I wouldn't expect them to be rose cut, which I'd expect to have a foil backing rather than the open backing you see in the photo.

Rose cut diamonds were invented in the 1400s and made popular in the Georgian Era (the 1700s). Rose cut diamonds have remerged as an ethereal, antique-inspired alternative to more traditional diamond cuts like brilliant cuts. They were one of the first cuts of diamonds, cut by hand by skilled diamond cutters to optimize sparkle in candlelight as they were made before electricity was invented.

Rose cut diamonds from the 16 and 1700s often had a foil backing and be in a bezel, like those shown on the ring below.  That is unlike more modern diamond rings that are set elevated so the light comes in from the bottom through the pedestal.  However, I do know of one 1715 Fleet diamond ring that didn't have foil backings for the stones.


But the mystery item does not seem to be a ring.  It does seem, as copilot suggests, to be part of a larger more complex piece.

 It also seems to me that some of the imperfections described by Copilot are due to wear or damage after loss rather than the method of manufacture. 

Here is a link to an interesting resource on 18th century jewelry.

And here is an excerpt.

Rose cut diamonds with a flat base were common in the 16th and 17th centuries.  

Old mine cuts (early-mid 1800s) feature squarish cushion shapes with high crowns and prominent culets, designed for candlelight performance with romantic, hand-crafted irregularities that create a warm inner glow

Old European cuts (late 1800s-1930s) introduced the first truly round diamonds with improved symmetry and light return, representing the bridge between pure craftsmanship and emerging scientific understanding of optics

Gemstone cutting methods improved dramatically in the 1700s and allowed gemstones to be manipulated in unique ways depending on client preferences. The table cut was square with a flat top and bottom. The rose cut rounded out a stone or diamond and gave it a domed top and flat bottom.

The old mine cut was especially popular and featured a rounded square shape with many facets. The cabochon cut was similar to the rose cut, in that it had a defined rounded top and flat bottom. Finally, the briolette cut shaped stones into a faceted teardrop, which featured on many women’s jewelry pieces.

I'm not so sure about bullet point one, I but generally agree with the rest of what Copilot says. and can't rule out the possibility of the item being old.  I suspect it is old but am not sure how old.  And it might not be jewelry, but if it is, it seems to be more complex than a simple finger ring, perhaps, as Copilot suggests, a locket or something like that.  It seems much of the item is missing, and we have little to suggest the actual size of the complete item as well as the purity of the material.  I haven't been able to come up with a guess about what the item is and can accept the possibility of it being from something larger and more complex, like maybe a religious or decorative item.

For example, here is the famous 1715 Fleet Pelican of Piety artifact. 



AI provided some very useful comments, but this seems to be a tough one.  Feel free to add your comments or corrections.  

I always learn a lot from researching mystery items, even when we can't come up with a definitive final answer. 

It doesn't hurt for a detectorist to learn a little about jewelry, gemstones, and settings.
