It's much harder cutting a long rectangular diamond, and getting it to be bright in the middle.
This stone solves that issue in spades - it's bright all over! Flashes and rainbows.
The clarity characteristic causing GIA to call it an SI1 is a tiny line, deep inside - the stone is totally eye clean- with no transparency issues whatsoever.
I can envision many different setting ideas... bezel, three stone, halo... totally up to you!
Let us make it happen!
