Here's a super well cut Asscher diamond - that's a starting and stopping point for me.
If it ain't super well cut, we ditch it.
That's one of the great things about lab diamonds. We don't need to make compromises in terms of cut.
In terms of color and clarity, that's also the case in this stone. Totally colorless, perfectly eye clean VS1.
Put it all together and you get flashes and rainbows.
It's large. It's graded by GIA.
A totally no excuses diamond.
