Purdy 2 (BEAD31.JRG)
By Jeff R. Graham
Copyright 2007
Angles for R.I. = 1.54
224 facets
16-fold, mirror-image symmetry
96 index
L/W = 1.000
H/W = 1.068
Vol./W^3 = 0.457

 

Addition # 14 – NOTE: A temporary girdle can be cut using the P1 settings. This works well in about any material and I like it in light to medium saturated material.
