Quartz (Amethyst, Citrine, Ametrine, Smokey, Rose)
Knight (BEAD10.JRG)
By Jeff R. Graham
Copyright 2007
Angles for R.I. = 1.54
40 facets + 16 facets on girdle = 56
4-fold, mirror-image symmetry
96 index
L/W = 1.000
P/W = 0.350 C/W = 0.350
H/W = (P+C)/W+0.02 = 0.719
P/H = 0.486 C/H = 0.486
Vol./W^3 = 0.304
Addition # 14 - This is quick and easy to cut. It’s made to go on a thin chain and have a nice edge look. The drill hole should be ground out with a small burr bit to fit a round bead, what ever size looks correct.
