L/W = 1.000 P/W = 0.415 C/W = 0.159
H/W = (P+C)/W+0.02 = 0.595
P/H = 0.698 C/H = 0.268

Addition # 2 - A nice quick no-brain required to cut design. This works very well for thin pieces of material. As the stone gets larger a table is a good idea, cut to meet C2, C3. I have a lot of Peridot that seems to come out of the ground in layers, this design works well for that shape. I use this in pendants and earrings, 1/2-4cts. Cut in refractive indexes 1.67 to 2.14 (89.3%) with no changes.
