Locating a stone

[danjmac]

Hello -
First of all thanks to all for providing the valuable information on this website, it has been truly helpful. I am figuring that this might be a Newbie question but I have tried searching for the answer and came out empty. I am upgrading my wife's ring and looking for a ~1.5 ct diamond with good spread and came across GIA report Number=2157079072. It is currently listed by on PS Solomon but they do not have it in stock. I wanted to get the expert opinion

1) Is this a good diamond for the 8K budget I have
2) How do I find out who actually owns the diamond? Would this even matter (price, speed etc?)

It's a lot of carat for the $, but that usually comes with a reason.
You need to see how eye clean this stone is as far as the inclusions. It's most likely not at that price/carat.
Spread is good and it should face up fairly large, but at the expense of depth/being shallow.
Numbers aren't horrible, but they're not ideal and you need more than just the GIA report.
You need to see the stone in person and have ASET, IdealScope, etc. to see what effect these numbers and inclusions /clarity have on its performance.

That's pretty close to what's known as a 60/60 stone. https://www.pricescope.com/wiki/diamonds/60-60-proportioned-diamond

60/60 in and of itself isn't bad, as long as all the other angles play nicely together. And this stone scores a respectable 1.9 on the HCA (excellent, within TIC range). But due to the low crown angle and large table it will likely not be as fiery (colored light return) as a traditionally cut ideally proportioned stone.

It has potential. BUT you now need an idealscope image to assess light performance, which I don't think SB can or will do.

I typed in GIA and the cert number 2157079072 into google, and it looks like ID Jewelry has the same stone (which leads me to believe no one actually has it in their physical possession right now). I believe IDJ can perform more advanced light performance tests (ASET, idealscope? Someone correct me if I'm wrong).

But my advice would be, if you are looking for the best stone possible, to stay with proven PS vendors (many of which offer PS member discounts) who can perform tests such as ASET and idealscopes. Stick with AGS 0 stones (which are already shown to be the cream of the crop) or GIA Excellents that score under 2 on the HCA, then ask for an idealscope.
