Cuts of beryls

0 votes

I'm new to gems and was wondering about the choice of cuts used with beryls. I know that emeralds are suited to the emerald cut in particular because it can be a bit more brittle than the other beryls but why are they so versatile? Is it due to the hexagonal crystal format? Or is it more to do with its hardness and in distinct cleavage? I'm a bit confused. Thanks

Beryl is 7.5 - 8 on the Mohs scale so not so soft nor brittle. Although struck in the wrong place even a diamond will take damage due to the cleavage caused by the individual crystalline structures.

Beryl can be cut into almost any shape and give a good to excellent lustre when polished. I have Emerald in every possible cut and even a couple of carved ones.

I think the final decision a lapidarist takes depends on the rough when they examine the inclusions, colour zones, cleavage and what a customer wants, nothing to do with the specific properties of Beryl.
