This lovely unheated Montana sapphire is gorgeous bright lime green color–a very rare and unusual color for a Montana sapphire (or indeed any sapphire). The gem has outstanding natural clarity, with just a few tiny rutile crystals, only visible with a 10x loupe. The high clarity makes it a bright and scintillating gemstone in the hand.
This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 1.06 carats and measures 6.1 x 3.9 mm; the perfect size for an engagement ring.
