85.6% Light Return
Angles for R.I. = 1.73
25 facets + 8 facets on girdle = 33
2-fold, mirror-image symmetry
96 index
L/W = 1.250 T/W = 1.027 T/L = 0.822
P/W = 0.537 C/W = 0.145
H/W = (P+C)/W+0.02 = 0.702
P/H = 0.765 C/H = 0.207
Vol./W^3 = 0.446

Addition # 7 – The L/W can vary on this with no problems. The corners are determined by the P4, P5 meet. If the stone is large the P3 can be tough to polish. I designed this for a ring with the bars on the crown running along the length of the finger. It will work well in man-made Sapphire and CZ.
