L/W = 1.051 T/W = 0.276 T/L = 0.262 P/W = 0.389
C/W = 0.282 H/W = (P+C)/W+0.02 = 0.691 P/H = 0.563 C/H = 0.408 Vol./W^3 = 0.209

Addition # 10 - Cut in refractive indexes 1.54 to 1.93 with no changes. This is designed for light saturations and is ideal in Rose de France. The star effect shows better in a large stone. I like it in 10mm to 16mm. It is easy to cut.
