If anyone has any information that can help, I would appreciate it. We recently found what appears to be a great deal on an engagement ring with an Old European Cut stone set within a modern replica of an antique setting. The stone is from around the 1930's.

There is no certificate with this ring from the GIA or IGL or anyone though I don't know why. The information I got from the jeweler, which is a very reputable jeweler who deals in Estate Jewelry is listed below. We are trying to determine if this is a good deal for this type and cut of there isn't alot of information out there on how to gauge quality of old stones. I know much of it has to do with whether or not you love the ring and the stone, as older diamonds are most likely hand cut as opposed to laser, and have alot more character. We really like the ring and think its a great deal, but wish we had more information on how to interpret the data we do have.

Here's the info:

1.31 carat old European cut diamond with I color and VS1 clarity is the center stone. It's set within a 4 prong platinum open engraved'basket' setting, allowing for movement of the light from the diamond. The shoulders of the ring are set with about .12 carats of baby channel set diamonds. The ring has narrow shoulders and band, between 1.7mm-2.1mm. The jeweler could not tell me polish or symmetry of the main stone, but did say that the table was 54% and that the depth was 4.2mm (they did not have a way to convert that to % I guess). Diameter is 6.8mmx7.1mm.

The price that was on the tag was $9k but they offered it to us for $7,500. They have had it for a few months, and at our last discussion--because she knows we are serious, she offered it to us for $7,200 (with 7.25% tax in our state). So it's a pretty decent discount off an already good $9k in our eyes..we love the stone, the size is great, and it is very sparkly. If you view the ring sideways or face up, it looks very clean and white.

Overall its a gorgeous ring and we love it. We just want to be sure we aren't getting taken for a ride with the pricing. From what I know about regular round brilliant, more modern diamonds, this is an outstanding price. I just don't know how to compare an old Euro cut to something that we see today. Also, from an experienced there really any difference between an H color and I? The I looked very white to us, even set in platinum, and I couldn't see alot of difference when I compared a D color ring to the I one.

In any case, any information or suggestions or comments are welcome. We are trying to make a decision in the next few days as we don't want to miss out on the deal or the ring as its one of a kind (because of the hand-cut stone). With my luck..we'll decide we want it then it will be gone! Also, if we do decide to get it, how do we have it appraised, or can we have it appraised before purchase? Does it need to a be an antique jeweler or ?? Is it a black mark that it does not have a certificate?

Thanks in advance!

Mara, sounds like you fell in love with this one, and if the price is good for a modern day cut, then you probably have yourself a deal! I'm sure member OldMiner could help you out.

I would say that a stone of that size was not common in the 30's (if you look at most antique enagagement rings, they usually have a very small diamond enhanced by white gold). I'd be interested in knowing who the stone actually belonged to!

The seller seems to have come down a bit = anxious to sell it. If you're at $7200, I'd offer $7000. Worst case is you get a "no" but atleast you tried. Good luck!

OldMiner, where are you?!

Old miner does have a chart for old european cuts but it doesn't sound like you have enough informationt to determine where it fits...

If you love the ring and are happy with the price, then all seems well. If it helps to have some comparison, you could look at the rings/prices are, and

Good luck and let us know what you decide!

I love old european cut stones, they are definitely each unique. however, the I in color bothers me--for $7200 you should be getting at least a G-H in color! Especially if it is set in platinum. you will be able to see the faint yellow color in a platinum setting. If you are set on the ring, then I would try to talk them down by several thousands, especially since they are offering no appraisal! If the jeweler you buy it from can''t appraise it, then how do you really know what you are getting? You might want to try Leigh at He is a very reputable dealer, who specializes in antique wedding and engagement rings. I have purchased several pieces of jewelry with old european stones from him and couldn''t have been happier with the stone and price. For example, my .60 carat old european diamond ring in platinum with side stones was (G in color, VS2 clarity) was very reasonable at $1800! And, after having it independently appraised by a friend who is also a jeweler, it was valued at $4200! Good luck!

Oh Mara, that sounds so beautiful! Is there anyway they''ll sell it to you with a long enough return period so you can have Dave Atlas appraise it?

JokerWatts -- I''m sure Mara appreciates the advise, but, I think you may be a little late with it ;-)
