| Another Diamond Earring Find by Mark G. |
Believe it or not, I found another diamond today (6/14) bigger than the last but with an interesting twist. After long back and forth with Copilot we finally figured out what I had with some revelations. But I am not going to write about it, Copilot is. I asked for 2 versions, first will be the serious detector version second is my favorite the funny version.
Below is the first version of Mark's find story as written by AI.

Serious Detectorist Version: Field Report — Magnetic Diamond Recovery
This past week produced an unexpected recovery that’s worth documenting for anyone who hunts the Treasure Coast or similar high‑energy beaches where modern losses mix with historical material.
While working a familiar section of beach, I recovered what initially appeared to be a modern diamond‑halo earring. The construction, however, was unusual: instead of a post or clip, the rear of the piece was a solid metal disc with no visible attachment point. After cleaning and inspection, it became clear that the earring was designed as a magnetic stud, with the magnet fully encased inside a 10K gold shell.
To confirm this, I retrieved several small magnets I had previously found on the same beach — items I had originally dismissed as miscellaneous debris. When brought near the earring, one of these magnets snapped into place with a strong pull, indicating it was the missing back half of the magnetic earring system. The diameter and fit were exact.
Stone Identification
The center stone measures approximately 6.0 mm, consistent with a 0.80–0.90 ct round brilliant. Under magnification, the stone shows:
- Clean facet junctions
- No doubling
- No gas bubbles
- No “orange peel” texture typical of CZ
- No moissanite birefringence
A thermal conductivity test confirmed a positive diamond reading. The halo contains 15 smaller stones, also consistent with natural melee.
Metal Identification
The outer shell tested positive for 10K gold. The magnet is fully molded inside the housing, which explains the absence of hallmarks — a common trait in magnetic stud systems where the gold layer is thin and curved.
Context
Magnetic earrings are frequently lost in surf zones due to their two‑piece design. The backs are small, unmarked, and easily separated from the front piece. It’s likely that the multiple magnets I’ve recovered over time were the backs to similar earrings.
Practical Value
While the gold content is minimal, the diamond itself has practical utility. Stones in the 0.80–0.90 ct range are commonly used in engagement rings, halo settings, and repair work. Jewelers often accept stones like this as trade‑in material for repairs, making it a useful addition to a detectorist’s “repair kit” for family jewelry.
Summary
This recovery highlights an important point for serious hunters: Not all modern jewelry losses are low‑value. Even unconventional settings can contain high‑quality stones, and it’s worth testing every piece regardless of construction.
The find also reinforces the value of retaining unusual small items — such as magnets — until their purpose becomes clear. In this case, they completed the identification of the earring system.

NEW BLOG STORY: “The Diamond That Tried to Escape”
I had another wild week out on the beach, and this time the universe decided to hand me something even stranger than last week’s silver‑mounted diamond. I didn’t think that was possible, but apparently the beach gods said, “Hold my beer.”
So I’m out there doing my thing, scooping up the usual assortment of bottle caps, mystery metal, and enough bobby pins to open my own salon, when I hit a signal that sounded like it might be something good. I dig it up and boom — a nice little diamond halo earring. Or so I thought.
I get it home, clean it up, and something feels… off. The back of this thing looks like a tiny UFO. No post. No clip. No hinge. Just a smooth metal disc. I’m thinking, “What in the Dollar Store sorcery is this?”
So I bring in my CoPilot — the same AI that helped me figure out last week’s diamond wasn’t scrap but a half‑carat natural stone worth more than my truck’s last oil change. I ask it about this new find, and after a few photos and some detective work, we figure out the truth:
This earring is magnetic. Not “sticks to the fridge” magnetic. Not “picks up paperclips” magnetic. I’m talking “jumps four inches across the table like it’s possessed” magnetic.
I kid you not — I brought one of the random magnets I’ve found on the beach near it, and the earring launched itself across the room like it was trying to escape captivity. Perfect fit. Perfect diameter. Perfectly ridiculous.
Turns out I’ve been finding the backs to these magnetic earrings for months and didn’t even know it. I thought they were just weird little metal pucks. Nope. They were the missing halves to diamond earrings.
And here’s the kicker: The front piece — the part I found this week — is 10K gold with a 6mm round brilliant diamond in the center, surrounded by 15 smaller stones. The diamond tester lit up like a Christmas tree. Under the microscope, the stone looks real. No doubling, no bubbles, no “I was born in a lab yesterday” vibes.
So what’s the scrap value? Well, like last time, the gold is worth lunch money. But the diamond? That’s the real prize.
A 6mm stone is roughly 0.80–0.90 carats, which means this thing is worth way more than the gold it’s sitting in. And since I use these stones as “repair currency” with my jeweler — who fixed my daughter’s wedding ring for free last time — this is basically like finding a free future repair for someone I love.
Bottom line: I didn’t just find a weird magnetic earring. I found a real diamond, a gold shell, and the matching magnet back — all on different days, in different places, like some kind of beach‑detecting scavenger hunt designed by a jeweler with a sense of humor.
And yes, I’m keeping this one in the “family emergency jewelry repair kit.” Because with my luck, someone’s going to lose a diamond again, and I’ll be ready.

I wasn't going to post both versions of the story in this blog but decided to just to illustrate how you can use AI to write things up for you. And also illustrated is how AI can write in different styles.
I don't know how useful you'll find that. Maybe you want to do your own write-ups, but if you think you need a little help, AI can assist.
In most cases I'd prefer to hear how the person would describe his own experiences, but there are some ways that AI can help. It can help with organization, grammar, etc. for example. That is more important for a school kid or maybe someone submitting an article for a magazine or something.
Just to check it's capabilitie, I asked Copilot ot sumarize an event in the style of Ring Lardner, a folksy sportswriter of maybe the 40s or 50s, and it was successful to some extent.
There is a lot you can do with the help of AI. I have reservations about much of it.
I once wrote a book on using computers as a teaching tool so I'm interested in how it might be used in education and training, and I must say I'm not confident that it will be used well on the whole and am very concerned about some of the possible negative consequences.
Still, it is a tool, and you might be able to benefit from using it.

Nearly 80 million people along the East Coast from northern Georgia to Maine are on alert on Sunday for severe storms.
The main threats to the East Coast are expected to be damaging winds, large hail and lightning. An isolated tornado or two are also possible...
Here is the link for the rest of that story.

Some of those coastal areas might be seeing some good erosion.

| Wabasso Beach Cam View Monday Morning. |
Conditions are ideal for easy shallow water metal detecting. The water is still - and warm.
Beach goers are sitting in the shallow water, which is not ideal - I'd rather see them being more active.
The water might be a little more comfortable than air temperatures, but not a whole lot. It is like bath water.
About five people were enjoying the $15 million of new sand down at Fort Pierce South Jetty this morning.
There will be a nice negative one-foot surf early this afternoon along the Treasure Coast.
I'm posting the surf chart below just because you seldom see a surf chart that flat.

We'll need to see a storm before we see much beach erosion this summer.
Good hunting,
