L/W = 1.073 T/W = 0.383 T/L = 0.357 P/W = 0.515
C/W = 0.246 H/W = (P+C)/W+0.02 = 0.781 P/H = 0.660 C/H = 0.315 Vol./W^3 = 0.292

Addition # 12 - Cut this in refractive index 1.67 to 2.14 with no changes. I designed this for Peridot or light colored Garnets. It is killer in any lightly saturated material and also works well in Zircons. Note: C2 only meets at the corners, cutting the tier to center point is the easiest way to make all the facets even.
