D inscription meaning?

[vitona526]

Hi, any ideas what the ‘D’ stands for on this ring? I assume the ‘D2.12 Ct’ refers to the diamond. Wondering if the ‘D’ means earth mined vs ‘LGD’ lab grown? Color is definitely not D.

I’m guessing D means the big diamond and d means the little diamonds. If this ring is vintage, older than five years, likely real diamonds. Can you examine inclusions (with a loupe)? That can also tell experts if real or lab.

I looked at the second photo and zoomed in. The diamond is (unless there’s a really authentic modern cutter out there) most likely mined, and antique. The girdle is typical of an antique cut diamond with a frosted hand-bruted girdle ranging from very thin to thin, etc. A newly cut antique style stone would have a less irregular girdle, it would also likely be polished and faceted. In general newly cut would be more symmetrical. Just from looking at it I’d be surprised if it wasn’t antique and very surprised if it was lab. Can you post a top down shot?

Wow, thank you!
This is the best top photo posted by the seller. It’s listed as OEC. They have an excellent return policy but getting more pics is like pulling teeth. It’s a good price. Strongly considering buying and taking to a local jeweler (and posting lots of photos here ) to check it out…. But not if it’s likely a lab or if you think it an obvious pass. I appreciate your thoughts!

This looks like a real old cut diamond, which would not be a lab. I’d send for it to see what it looks like, if return policy is good and easy. You could also ask the seller what they were told about it. The setting is modern. Some PSers might even be able to tell you who made it. Once you have better photos, PSers can help you decide about cut.

Thank you! I bought it. I’ll be back in a couple days/next week once I have the ring.

There are certainly some Lab diamonds being cut in the OEC style. Some may indicate this with laser inscriptions on their girdles and others may not be marked. They are not a common product, but don't assume anything.

Definitely won’t assume. As far as labs go, Guilty until proven innocent

Do these newly cut OECs have frosted girdles and asymmetry? Haven’t seen it. But in this setting (a popular style from five plus years ago IMO) and these markings, and color/tint, along with a larger table than a typical OEC, asymmetry and girdle frosting, I’d be surprised if it was modern cut and very surprised if it was lab.

OTOH that tulip style basket setting seems too plain and for someone to have put a coveted old cut in. So you may be on to something!

The old cut lab diamonds started heating up post pandemic. They are fairly common now. But In general they are either REALLY badly done or very well done. This stone has the vibe of later OEC or early modern brilliant. I’d be impressed if a modern cutter did this, but you never know.

In some Countries ie Japan they usually put the gemstone weights onto the shank of the ring. In this case the D would be for the weight of the large diamond and the d for the weight of the melee diamonds.
In terms of whether the gems are from the earth or lab grown, that distinction isn’t made, you would need a lab report or reading the inscription on the girdle to know that.
However, you can’t 100% rely on the ring shank inscriptions because people can and do replace gemstones in rings for a variety of reasons,

Very good points. And yes, I’ve never seen such inscriptions done customarily here in USA. Tulip setting is a popular setting here though.

Thank you for this info.
I found these photos on Etsy with a similar inscription. Seller is from India and this is a moissanite ring. I messaged the seller and asked what it meant, he said the ‘D’ was at the request of the buyer and had no meaning.

Ring will be delivered Monday and I have high hopes but low expectations.

I will post a new thread for opinions when I have it. I have a loupe and will look for any diamond inscriptions.
