This beautiful unheated Montana sapphire is a gorgeous bright mint green color–one of my favorite colors in the Montana gems.  The macro image shows a few natural feather inclusions in the gem, but they are not easily visible without a loupe at a normal viewing distance. In the hand this is a gorgeous gemstone, bright and scintillating!  I have factored these inclusions into the pricing, making this a tremendous value for the size and color.

This sapphire is faceted in my custom “Aurora” brilliant square cushion design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 1.99 carats and measures 6.5 x 5.0 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
