L/W = 1.000 P/W = 0.435 C/W = 0.225
H/W = (P+C)/W+0.02 = 0.679
P/H = 0.640 C/H = 0.331
Vol./W^3 = 0.292

Addition # 4 - This is fun to cut, and fast too. I like to cut this in dark Amethyst, it works well in sizes up to about 10mm for earrings. When setting the corners need to be protected, I usually just nick and polish them, so they are not sharp. This works well in Tourmaline and Topaz. Cut this in R.I. 1.54 to 2.14 (90.7%) without changes.
