Angles for R.I. = 1.54
47 facets + 8 facets on girdle = 55
2-fold, mirror-image symmetry
96 index
L/W = 1.330 T/W = 0.544 T/L = 0.409
P/W = 0.511 C/W = 0.248
H/W = (P+C)/W+0.02 = 0.779
P/H = 0.656 C/H = 0.319
Vol./W^3 = 0.428

Addition # 1 – A preform is a must L/W 1.33. The cutting order on the pavilion can be changed. This design cuts fairly easy (with a preform). The P6 facets can be varied. This is a fairly deep design and will help darken light colors…
