L/W = 1.000 T/W = 0.276 T/L = 0.276 P/W = 0.420
C/W = 0.208 H/W = (P+C)/W+0.02 = 0.648 P/H = 0.648 C/H = 0.322 Vol./W^3 = 0.210
Addition # 10 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is not hard to cut and makes a very nice stone. I like it in medium saturated materials. It makes a nice stone in Tourmaline and is good for thin nodules.
