10ct Heated Kashmir Crystal Specimen

This 10ct thermally enhanced Kashmir specimen is a transformation from a 'pastel' to a 'royal blue' color.   The specimen is available for a short time until we decide to facet, carve or cab the colored stones inside.

Deciding how to process a sapphire is only possible by experience.  The gemstones have a different value based on the final result and market trends.  Some rough gemstones are sold as mineral specimen and others are cut, carved, tumbled or treated.  

This stone was a classic corroded bipyramid Kashmir with pastel color before enhancement.
