[QUOTE="Dihusky, post: 593237, member: 10304"] From the 'native' cuts I have seen, the finished cuts are very obviously based on carat yield not on accurate angles, many tend to have bulky pavilions with a lot of little facets, but weigh more than what a precision cut stone would. The Thai jam peg machines are good for fast repeatable cutting by a skilled operator, but they don't have a precision angle setup, not a multiple index system, the index is something like a plastic octagon with the dop/peg wedged in with some paper and the finished angle is determined by the depth of cut. I've got a couple of native cut stones which I bought specifically for re-cutting and to use as an example of how different the same stone can look following a precision cut. I'll get them cut once I've finished the latest batch of Sapphires and post the before and afters. [/QUOTE]
