Faceting Design Diagram: CZ “X” – Cubic Zirconia


Cubic Zirconia

CZ “X” (CZ13.JRG)
By Jeff R. Graham
Copyright 1997
77% Light Return
Angles for R.I. = 2.20
59 facets + 8 facets on girdle = 67
2-fold, mirror-image symmetry
96 index
L/W = 1.000 T/W = 0.551 T/L = 0.551
P/W = 0.399 C/W = 0.201
H/W = (P+C)/W+0.02 = 0.620
P/H = 0.644 C/H = 0.324
Vol./W^3 = 0.283

Addition # 2 – The light return is better than it shows, there are a lot of trapped rays. It is a little tricky to cut at the P8,P10. Cut in any CZ, 2- 12cts.
