Angles for R.I. = 1.54
22 facets + 4 facets on girdle = 26
2-fold, mirror-image symmetry
96 index
L/W = 1.336 P/W = 0.457 C/W = 0.244
H/W = (P+C)/W+0.02 = 0.722
P/H = 0.634 C/H = 0.339
Vol./W^3 = 0.547

Addition # 6 - This is fun and fast… This works in almost any material with no changes. L/W is not critical on this design and it can vary a little with no problems. I really designed this for Tourmaline crystals, it will yield very well, with steep ends to help with dark "c" axis stones. This design does darken a bit…
