Faceting Design Diagram: “Malt” Squared – Quartz – Citrine, Amethyst, Ametrine, Smokey, Rose


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

“Malt” Squared (QTZ46.JRG)

72.6% Light Return
Angles for R.I. = 1.54
53 facets + 8 facets on girdle = 61
4-fold, mirror-image symmetry
96 index
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.
