80.5% Light Return
Angles for R.I. = 1.54
24 facets + 4 facets on girdle = 28
4-fold symmetry
96 index
L/W = 1.000 P/W = 0.494 C/W = 0.155
H/W = (P+C)/W+0.02 = 0.668
P/H = 0.739 C/H = 0.232
Vol./W^3 = 0.266

Addition # 2 - Here is a design that cuts fast and makes a great pair of earrings, which is what I designed it for. Cut it in the 4-8mm range in about any material. A preform will help save waste, Quartz is cheap (in lighter colors). I usually don't. On a larger stone a table is a good idea, cut to meet C2, C3. Cut in refractive indexes 1.54 to 1.93 with no changes.
