Round Stones only
Diamond CUT GRADE was introduced by the GIA for round stones only in 2006 that’s why you don’t generally see it listed on fancy shapes.
We where there
ComparetheDiamond.com (formerly diamondgeezer.com) were one of the few UK manufacturing jewellers to be invited to the Antwerp launch.
A Duplicated Principle
Other gem laboratories have seen the need to follow, to emulate(?) the GIA and some specify cut on fancy shapes.
Only their opinion
It is interesting to see that other cutters & gemmologists are beginning to apply cut grades to other shapes, these may or may not be listed on the certificate and must be viewed as the seller’s opinion.
