The Nice Ice and SuperbCert diamond are the same, but obviously in house at Nice Ice.
The two GOG stones. THey have different crown faceting. One gives off glare in .gem....not sure what to think of that. No preference for either arrangement outside of .gem.
anyway, if you want one of the GOG stones, you could have Jon or Tim discuss the finer points with you.
I believe all Nice Ice stones are owned by them...
"We only list and represent diamonds which we have personally evaluated and purchased for our exclusive inventory.
The diamonds listed below are real, in-house and available... We do not list "virtual inventory" that we don''t have like those other guys."
And the listing on SuperbCert may not have been updated. I know that sometimes they have not been able to get a specific stone they listed.
I haven''t looked really hard at them, but they all look like stunning princesses.
For my money, I''d take the first stone from GOG, providing its eyeclean, which it looks like it may be. It is very square, measures the largest, and has the kind of table/depth combo I like. The table on the second GOG stone is bigger than I like. THose are some gorgeous choices, though!
