Addition # 1 - This design is a little hard to cut. The steps on the bottom are about even, the top steps get smaller as they go to the table. The steps can be cut to your own taste, 1-16cts. Cut in refractive indexes 1.54 to 1.93 (83.9%) with no changes. This cuts well in Beryl, Feldspar (Sunstone),and Topaz.
