L/W = 1.000 T/W = 0.609 T/L = 0.609 P/W = 0.557
C/W = 0.141 H/W = (P+C)/W+0.02 = 0.718 P/H = 0.775 C/H = 0.197 Vol./W^3 = 0.296
Addition # 11 - Cut in refractive indexes 1.54 to 2.14 with no changes. This is excellent in about any colored material and works well in Beryl. It cuts fairly easy and fast I prefer lightly saturated materials. Note: The girdle can be cut in first and the P1 cut to meet so that center point is not needed and it saves rough.
