I attempt to accurately represent and describe cut stones and rough
as to appearance, size, origin and fully disclose any known
treatments in its description. Because you view the images on a
different monitor with different settings, color is particularly fickle
to represent, but I do my best.

Angles are for R.I = 2.17
57 Facets  +  8 Girdle Facets  =  65  Total Facets
8-fold radial symmetry
96  Index
L/W = 1.000  T/W = 0.572  U/W = 0.572  P/W = 0.439  C/W = 0.169
Volume/W e3  =  0.227
Cutting Remarks  -  This is named after a very special friend of mine. The angles work without changes from R.I. of 1.59
to 2.17.  But it is best at 2.17.
