3.60-Carat Blue-Green Montana Sapphire (Heated)

3.60-Carat Blue-Green Montana Sapphire (Heated)



A beautiful medium blue-green heated Montana sapphire, quite large for the locality at 3.60 carats.

In stock


This beautiful heated Montana sapphire is a lovely medium blue-green color–the classic Montana sapphire color.  The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. There are a few tiny discoid inclusions present in the gem, but they are not easily seen without a 10x loupe and do not effect the brilliance or durability of the gem in any way. I have factored the inclusions into the price, making this a good value for the size–Montana sapphires of this size are quite rare.

This sapphire is faceted in my custom “Testudo” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 3.60 carats and measures 10.1 x 7.5 x 6.2 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
