This beautiful Montana sapphire is a beautiful medium blue color with some slight color zoning of lighter blue to almost colorless. Overall, however, the colors mix in the hand and the appearance is a beautiful rich medium blue. Unlike most of the Montana sapphires I offer, this one has been heated. The heating was done here in the United States, in Montana, and was the only treatment done. It is permanent and stable. The heating dissolved the rutile silk, allowing the blue color to develop, and making the gem clear and transparent.
This sapphire is faceted in my custom “Aurora” brilliant oval design, created and optimized for Montana sapphire; the result is a glittering beauty of a gemstone. The gem weighs 1.96 carats and measures 6.5 x 4.9 mm; the perfect size for an engagement ring.
