L/W = 3.010 T/W = 0.945 T/L = 0.314
P/W = 0.450 C/W = 0.327
H/W = (P+C)/W+0.02 = 0.797
P/H = 0.564 C/H = 0.411
Vol./W^3 = 1.341

Addition # 8 - This is designed for long narrow Tourmaline crystals, and makes a nice stone in about any material. I use it for the occasional multi-colored long crystals I come across. This is fairly simple but the keel can be tough to polish because of it's length. Cut this in refractive indexes 1.62 to 2.14 with no changes.
