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  -  This material was a dream to cut!  It refused to give me any problems.  The finished
stone is very bright and has a lot of sparkle.  Give this design a chance, and you won't be sorry.  Works as is
