I have been looking into OEC diamond lately and found one at a jewelers store. Here are the diamond specs:

Measurement: 6.18 x 6.41 x 4.05 mm
Carat Weight: 1.02
Color Grade: J
Clarity Grade: VSI
Cut Grade: Good
Polish: good
Symmetry: Fair
Flourescence: None
Asking Price: 5600

It looks like an OEC to me until I saw the GIA certificate for it; it was stated as a "ROUND BRILLIANT". I asked and was told:

"GIA doesn't recognize the euro cut so they categorize it as a Round Brilliant. Every diamond that's not a round brilliant is technically a modified round brilliant cut."

I'm quite doubtful from the given info by the jeweler and not sure if I should purchase the diamond or not. Can anyone please help verify the given info.
 
False. GIA does have a Old European and a Circular Brilliant designations.

BUT.
GIA's criteria for OECs is VERY restrictive. Circular Brilliant is very restrictive too.

So it is true that MANY of what WE would consider OECs are listed as Round Brilliant on their GIA lab reports as a result of not meeting those overly strict criteria.

BUT to say that GIA doesn't HAVE an Old European designation is in the strictest sense false.

That doesn't mean however that he is wrong in his assertion that the stone is an OEC despite it's GIA designation of Round Brilliant.

:wavey: Do you have pictures?

Thanks Gypsy! :wavey:

Here are the pictures to the diamond. The diamond is mounted in a setting and the picture angle is off a little. The closer one was taken by me and other was sent by the jeweler.

Looks like a very small culet. Wouldn't have qualified for any other designation exception round brilliant as a result. ;))

That's the answer he should have given you.

Pretty ring. I like it.
 
Thanks Gypsy for the clear explanation!!!!

Thanks for this! I was wondering why mine was considered a circular brilliant! Now I know!
 
Thanks Gypsy for that explanation, I had the same questions as the OP in regards to my wife's new old euro. :appl:
 
The nomenclature can be very confusing. Old European cuts aren't necessarily old and aren't necessarily European. Meanwhile, round brilliants don't have to be particularly round or brilliant. Going the other direction leads to 'Old Mine' cuts, which have nothing to do with either age or mines and is a phrase that GIA doesn't currently use.

Don't loop on it. It's a bit like a lab referring to a Coke as a 'cola beverage' in their analysis. It's weird, but it's actually a reasonable approach if you think about it.
