L/W = 1.330 T/W = 0.469 T/L = 0.352
P/W = 0.437 C/W = 0.252
H/W = (P+C)/W+0.02 = 0.710
P/H = 0.616 C/H = 0.355
Vol./W^3 = 0.316

Addition # 3 -This is hard to cut and should be in a larger size, it works well in CZ also. It should be cut in a large size because of the number of facets and meets. Light to medium color material,2-24cts.
