River Green Faceted Montana Sapphire

Up for sale is a 5 X 3.5 mm faceted round medium River Green Montana Sapphire weighing .90 carats. It has been heated.

I purchased several carats in 2011 from a certified gemologist. He was hired as a liquidator for a failed sapphire mining company hoping to turn their inventory into some small return to the original investors. The liquidator depended on the records of the company for the provenance.

The sapphire is from the Lower Cottonwood Mine near Deer Lodge, Montana. It was heat treated in an unknown location and faceted with a brilliant cut with the requisite number of facets in Sri Lanka. The gem cutlet comes to a point.

I am selling this sapphire for $500. per carat = $405. USD. The Natural Sapphire Company is selling a similar Montana Sapphire for $1000. per carat.

I have been buying and selling faceted gemstones for 17+ years. Inquires may be sent to agardenbum@gmail.com Item #5.
