 Gemstone Faceting Rough

No high-grading please when purchasing lot quantities of faceting rough.
You must return an entire lot for a refund.

This does not apply when purchasing single stones.

Faceting Rough is identified by a 3 letter coding system.  This system was originated by Glenn Vargas many years ago.  I have added to it since that time.  It makes finding gem material easier and it makes invoicing that material more convenient.

o off from perpendicular (or it  will not polish)
