L/W = 1.051 T/W = 0.212 T/L = 0.202 P/W = 0.389
C/W = 0.223 H/W = (P+C)/W+0.02 = 0.632 P/H = 0.615 C/H = 0.353 Vol./W^3 = 0.183

 

Addition # 10 – Cut in refractive indexes 1.54 to 2.14 with no changes. This has a cool reflection and works in about any type of rough. I use it for earrings and it is fast and fun to cut.
