This beautiful heated Montana sapphire is a gorgeous sky blue color, reminding me of the “Big Sky Country” of Montana. The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. This gem has good clarity, with just one internal feather at one end. It is far less prominent in the hand than the macro photo implies, and does not effect the durability of the stone in any way. I have factored it into the price, making this gem a good value for the size and color.
This sapphire is faceted in my custom “Testudo” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 1.86 carats and measures 8.0 x 5.9 x 5.0 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
