L/W = 1.108 T/W = 0.474 T/L = 0.428 P/W = 0.447
C/W = 0.207 H/W = (P+C)/W+0.02 = 0.674 P/H = 0.663 C/H = 0.307 Vol./W^3 = 0.240
Addition # 12 - Cut in refractive indexes 1.62 to 2.14 with no changes. This is an easier design then "Glitter Drop", there is one less pavilion tier and is will work for smaller stones. Use light to mediumly saturated materials. Note: Cut to L/W, P9 can be cut in to help with P7.
