11 polished diamonds from E to L from one rough.
You may see here how color grade depends from size and cut of polished diamonds( the rough had color zoning also)
I know this is a random Qs which deviates from the original intent.
But for a 77ct rough, the total caret wt of the 11 stones is only 22.79ct.
Is that normal? Seems like a lot of wastage.
