82.6% Light Return
Angles for R.I. = 1.54
25 facets + 4 facets on girdle = 29
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.442 T/L = 0.442
P/W = 0.435 C/W = 0.169
H/W = (P+C)/W+0.02 = 0.624
P/H = 0.696 C/H = 0.271
Vol./W^3 = 0.285

Addition # 4 - This is fun to cut, there are no meets on the top at C3. Cut them as square as you can. This design has a lot of sparkle, you will be surprised. Cut in about any color and size. This works well in Tourmaline and Topaz. Cut this in R.I. 1.54 to 2.14 (92.5%) without changes.
