Gram Book 1 - This design is shallow for dark material and cuts a nice stone in the 1- 6ct range. I like it for earrings especially, because they sell very well and are different. A table can be cut (and should be) as the stone gets large. I like it without one for small and/or darker stones. The corners can be a little fragile, but in general are no problem. Cut in refractive index 1.73 to 2.14 with no changes.
