Cutting Instructions
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.

Cutting Remarks  -  Good from RI = 1.72 to RI = 2.17 without changes.  I wanted a basic checkerboard oval and couldn't
find anything I really liked, so this is the result.
