"Malt" Squared (QTZ46.JRG)
By Jeff R. Graham
72.6% Light Return
Angles for R.I. = 1.54
53 facets + 8 facets on girdle = 61
4-fold, mirror-image symmetry
L/W = 1.000 T/W = 0.463 T/L = 0.463
P/W = 0.479 C/W = 0.232
H/W = (P+C)/W+0.02 = 0.731
P/H = 0.655 C/H = 0.318
Vol./W^3 = 0.306
Addition # 1 - The P3 facets can be cut later, but it's good to have them roughed in for the P4(G) facets. It helps to have the table in before cutting the C4, they meet. Cut this in refractive indexes 1.54 to 1.93 with no changes. This design is good for light to medium material, 1-8cts.
