Table, Crown height, Crown %, Crown angle, Pavilion depth %, Girdle thickness and finish, Culet size and note if abraded or chipped, Brilliance on a score of Poor to Excellent, Proportion Grade (GIA scale of IA-IVB) and H&A symmetry noted if present
Cut evaluation tools:
I use an H&A scope, the Ideal-Scope, the ASET, a crown angle gauge, and a mm gauge built in to the ocular of my microscope. Other area of expertise:
I appraise vintage and period jewelry, and can discriminate between an old piece and a reproduction. Recent education:
My most recent educational event was the AGA seminar on red diamond?natural diamonds with induced color. Amazing, considering there are probably only 100 or so natural color red diamonds around.\n\n I have taken and passed the ASA courses, the ISA courses and the JCRS insurance appraisal course. I have written and taught several appraisal courses for ASA, including updating the Master Gemologist Appraiser course. I have taught appraisal courses in various universities throughout the country.
