Hi I'm a bit confused. I note that some jewler sites apply their own cut ratings to stones. eg JA has ideal, premium etc , and another site I've seen as 4 and 5 star ratings. these sites also list the cut rating from the GIA certificate separately (eg the stone may have a Gia excellent rank, but only 4 stars by the jewler site (h+a stones have their own ranking).
However, I know that both of these sites do not actually have the stone in their stock, so presumably their ratings can only be based on the certificate. How do they derive their cut rating then?
I thought it may have been a hca rank, but some of the stones ranked as 5 star, or ideal (with Gia certification of excellent) do not get a great hca rank.
Comments welcome! thanks.
