Angles for R.I. = 1.56
41 facets + 8 facets on girdle = 49
8-fold symmetry
96 index
L/W = 1.000 T/W = 0.446 T/L = 0.446
P/W = 0.445 C/W = 0.234
H/W = (P+C)/W+0.02 = 0.700
P/H = 0.636 C/H = 0.335
Vol./W^3 = 0.260

Gram Book 1 - This is the first aqua I did, it is a simple stone and cuts fast. The P3 facets cut very fast! The Pavilion gives this stone a very nice circular flash, 1/2-6cts. Cut in refractive index 1.56 to 1.93 (84.3%) with no changes.
