hi all :)

i'm looking at some green diamonds and a few have GIA certs that say origin "undetermined" they look very natural...not that overly green obviously treated ones. i have a green already but would like another one... it's so tempting to buy stuff when i see them around :razz:

would you buy one? it looks very natural...

Depending on its price, it's some kind of a gamble.
I have a few undetermined greens which I am pretty sure are natural as I planned and cut them, I am just waiting for some future date and perhaps GIA will have more definite answers.

When a color is undetermined, as with greens more often then any other color, they wind up in limbo with regard to buying and selling. Most of the trade will avoid buying such stones. As stated previously, GIA is always working on future ways of determining if the color is natural or not on green stones as well as other colors.

I had this exact scenario last week Dan. A lovely marquise. The dealer had priced it as if it was say a D, but without clear solid paper work as a tread stone - it was 2-3 times the price. He called me in Australia from NYC pleading its virtues and how he knew the miners and cutters etc etc. He has owned it for 10 years and can not bear to part with it at treated prices.
Kind of like a limbo

I think you should avoid undetermined green diamonds at all cost. I met a particular seller who did not disclose the undetermined status of the diamond that he was planning to sell to me. It was a 2 carat yellow-green that was going for 18k, it was only after checking out the GIA cert that put me off big time.

Sounds like Mr Donda was trying to post his contact details and initiate direct contact re: a transaction, which is against PS Trade Member rules, meaning the post(s) was/were deleted.
