Angles for R.I. = 1.54
10 facets + 8 facets on girdle = 18
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.818 T/L = 0.818
P/W = 0.082 C/W = 0.082
H/W = (P+C)/W+0.02 = 0.184
P/H = 0.446 C/H = 0.446
Vol./W^3 = 0.967

Addition # 14 – This is easy, it is basically a cube. Start with a cube preform, and just cut in the 42 degree breaks on all the edges… The drill hole can be placed on any side you like, but I designed this to be drilled diagonally, from corner to corner. I originally put this with square black onyx beads. The cube was a nice rose Quartz diagonally cut.
