Faceting Design Diagram: Blue Max – Quartz – Citrine, Amethyst, Ametrine, Smokey, Rose


Quartz (Amethyst, Citrine, Ametrine, Smokey, Rose)

Blue Max (CHECK41.JRG)

87.3% Light Return
Angles for R.I. = 1.54
65 facets + 12 facets on girdle = 77
4-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.169 T/L = 0.169
P/W = 0.485 C/W = 0.203
H/W = (P+C)/W+0.02 = 0.708
P/H = 0.685 C/H = 0.287
Vol./W^3 = 0.286

Addition # 6 – Cut this in refractive indexes 1.54 to 1.93 with no changes. I like this in any medium saturated material. This works well in most man- made corundum colors…
