What is this cut?

[kemurphy]

First I want to thank everyone for all the help and amazing information I have received in the last two months of finding this website! Wow, there is a lot of incredibly knowledgeable people here!

My Mom has an antique wedding ring and I was wondering if anyone had any idea what the cut might be. She was told it was an old mine cut when she purchased the ring 15 years ago. Is that correct? It seems so round to be a mine cut. I apologize but this is the only picture I took of it. I hope it's clear enough to see the cut.

To my eye, it looks like a round brilliant in an antique style setting. But I'm certainly no expert.

i think it is a modern round.

It doesn't look like an old mine cut to me - it looks like a round brilliant.

It looks like an early round brilliant, but I'm not an expert as some of the "old cut" ladies are here.

That's pretty funny... shows how little I know about cuts of diamonds! I thought it was maybe a transitional or something like that as it is very different from my OEC and I thought it was no way a mine cut!

She has mentioned that it doesn't seem to have much sparkle compared to other rings. Is this probably because it's not the best cut?

 

[JulieN]

Yes, it looks like a not too great MRB. Largish table and splintery arrows is my guess.

looks like a round brilliant cut with large table around 66%-68%. A good sign to indicate that it isn't well cut.

In people's experience, is a poorly cut diamond like this a good candidate for re-cutting? About how much does that cost? Her diamond is estimated to be around 2 ct. I feel bad for my mom as she always feels like it's not as sparkly as other peoples. She will go into a jewelry store and they will offer to clean it as it looks "dirty" and apologies after as it's just her diamond!

It needs to be looked at by a pro to see if it can be recut. Any of the usual vendors should be able to have it checked out for you: Good Old Gold, High Performance Diamonds, Brian Gavin. I know Singlestone has done an antique-style recut for a poster before.

I think it is a transitional - great big table, early-modernish faceting that's period-appropriate to the setting. I think it looks lovely, going off that one shot, but if you want to recut it ... Singlestone, maybe?

Might be a European Cut (not a transitional or Old European Cut) Lang's Antiques site usually has a few.

I thing you should get an ASET scope (IdealScope) and take a look at it, or have an appraiser do it. Generally the better candidates for recut to modern RB proportions with H& pattern, without losing a lot of weight and diameter, are deep stones that have reasonably small tables. (At least, that's my observation.) Those with the large table and shallow crown angle need a lot of material removed in order to create a small table, a 34-35 degree crown angle, and about 15% crown.

I would just leave that stone as-is, unless it's extremely leaky. Some inclusions make diamonds not suitable for recut, too. Generally the recuts are very good, but not as good as the hand[picked diamonds at Good Old Gold, Brian Gavin, Whiteflash, etc.
