L/W = 1.155 T/W = 0.511 T/L = 0.442
P/W = 0.469 C/W = 0.202
H/W = (P+C)/W+0.02 = 0.691
P/H = 0.678 C/H = 0.293
Vol./W^3 = 0.271

Addition # 1 - This design is tough to cut because of the step cuts, and the small C6 facets (have to be exact) on the crown. This design is good for very light colored materials, notice it is not bright, but it has a lot of sparkle. Cut in refractive indexes 1.54 to 2.20 with no changes.
