Quality of cut and shape for cabochons


#1

I would be interested in hearing opinions of the standards and
specifications that gemstone appraisers apply in determining the
quality of cut and shape for cabochons. dome contour and depth. I am
particularly interested in calibrated stones, both oval, round and
cushions. I’m currently working in nephrite jade but I am looking at
other materials also.

Thanks for any thoughts.
