Gram Book 1 - This is a neat design for light to medium material and cuts well in about any size. I suggest that you leave P3 and C2 frosted (in light colored Quartz). I use a worn 320 grit, the ray trace is misleading, it has more reflection. When the facets are frosted, this has a flower-like effect. Cut in refractive index 1.54 to 1.93 (80.0%) with no changes. Note in 1.76 and higher the P1, P3 tiers are reflecting light, no need to frost them, if you do not want to. This is actually a pretty design and will help with light materials.
