Here's a super premium lab diamond. The cut is amazing.

Tough to achieve this type of results in a rectangular diamond.

There are large chunky facets, lots of fire.

Totally eye clean VS1.

Also completely colorless.

GIA graded F color.

There's a reason you don't see a lot of GIA graded lab diamonds.....well a few reasons.

IGI, although they are pretty accurate on colorless diamonds, still can't touch GIA's reputation.

The other reason is hundreds of reasons.

On a stone like this one at least a $250 difference in price between GIA and IGI reports.

Still, I think GIA does add more than that in terms of value.
