Honey Crystal, 6 ct. Natural Unheated/ Untreated Rough, Intact Double Terminated, Ceylon Yellow Sapphire Crystal from Sri Lanka 

This rare rough yellow sapphire crystal from Sri Lanka (Ceylon) is a magnificent specimen, It possesses a gorgeous strong golden yellow color with great uniformity and wonderful color banding. 

This crystal exhibits exceptional translucency while still maintaining a deep yellow color which is rare.

This special crystal is Gem quality but due to its unique banding of yellow colors, it was never cut and is worth more as a crystal specimen than it would be as a faceted stone if it were to be cut.

Due to certain export regulations in Sri Lanka, rough sapphire crystals are not normally allowed for exporting, permitting only cut and carved stones for export. This stone was acquired through a gem crystal specialist who traveled to Sri Lanka regularly and obtained special export permits for each crystal, something that is normally very difficult to do unless you buy in large parcels.
.
This stone is unheated/untreated making it very rare and valuable considering that 99% of ruby/sapphires (Corundum) are heated or treated in some way in today's gem market.

Due to the rarity of this stone, and the absolutely gorgeous translucent double-terminated crystal structure it would be advised not to use this stone for cutting or jewelry and instead to keep it as a crystal specimen, as this is a very rare, collectors' stone.
