Angles for R.I. = 1.54
33 facets + 8 facets on girdle = 41
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.284 T/L = 0.284 P/W = 0.458
C/W = 0.187 H/W = (P+C)/W+0.02 = 0.665 P/H = 0.689 C/H = 0.281 Vol./W^3 = 0.236

Addition # 11 - Cut this in refractive indexes 1.54 to 2.14 with no changes. This works well in Garnet. I designed this for small color spots and/or pale pieces of color. This is a reflector bottom to help prevent color mixing.
