This beautiful Montana sapphire is a wonderful shade of blue-green, a classic Montana sapphire color and one of my favorites. The color was developed by heating the gem in Montana, but no other treatments were made to the gem. The treatment is permanent and stable and not only develops the color, but also improves the clarity. This sapphire has inclusions that are visible in the hand. The inclusions have been factored into the price, making this a great value for the size and color.

I faceted this sapphire in my custom “Hyperbola” brilliant oval design. The design is very bright and creates a beautiful pattern of scintillation in the hand. The gem weighs 2.57 carats and measures  8.6 x 7.3 x 5.4 mm; the perfect size for an engagement ring.
