This beautiful unheated Montana sapphire is a gorgeous medium blue green color, similar to the color of a fine gem aquamarine. This sapphire is unheated and untreated in any way. There is a light amount of natural rutile silk that is proof of its unheated status, but it is not visible without a loupe. There is also a tiny feather off to one corner that will be hidden when the gem is set; its also not visible without a loupe.
This gem is faceted in a custom brilliant trillion design (a “trilliant”), modified and optimized for Montana sapphire. The resulting gemstone is incredibly bright and scintillating in the hand. The gem weighs 1.14 carats and measures 6.8 x 4.0 mm; it would an ideal stone for a unique engagement ring.
