This beautiful unheated Montana sapphire is gorgeous mint green color–green tinted by a hint of blue. Like many Montana sapphires, it can shift color–in daylight it can appear more blue-green than green. This sapphire is unheated and untreated in any way. There is a tiny amount of natural rutile silk that is proof of its unheated status and a tiny inclusion visible in this macro image, but neither of these are visible without a loupe.
This gem is faceted in a custom trillion design and cut to high precision; the result is a glittering beauty of a gemstone. The gem weighs 1.03 carats and measures 6.6 x 3.9 mm; it would an ideal stone for a unique engagement ring.
