P/W = 0.460 C/W = 0.226
H/W = (P+C)/W+0.02 = 0.706

Vol./W^3 = 0.279
Addition # 1 - This design is a little harder to cut than it looks, so watch the meets. It has nice flash and is not that hard to cut (for a modified square). Cut in refractive indexes 1.54 to 1.93 (85%) with no changes. It makes a nice stone in light to medium material, 1-6cts.
