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 = 1.62
67 Facets  +  12 Girdle Facets  =  79  Total Facets
6-fold radial symmetry
96 Index
L/W = 1.000  T/W = 0.384  U/W = 0.384  P/W = 0.438  C/W = 0.203
Volume/W e3  =  0.226
Cutting Remarks  -  The slight offset of P3 creates a lot of extra confusion in the reflections.  This can be cut from
R.I. = 1.54 to R.I. = 2.17, but it's best from Tourmaline to Garnet.
