This beautiful unheated Montana sapphire is a gorgeous medium green color, with a tint of blue. Like many Montana sapphires, this sapphire can shift color, appearing more pure green in some lighting while shifting to blue-green other lighting. This particular sapphire has a light amount of natural rutile silk–proof of its unheated status–and a few tiny natural inclusions. These are not visible in the hand without a 10x loupe, and in the hand the gem is bright and lively.
This sapphire is faceted in a custom brilliant oval design that I created just for Montana sapphire. I’ve named the design “Testudo” as the facet pattern of the crown reminds me of a tortoise’s shell. The gem weighs 1.14 carats and measures 6.5 x 5.0 x 4.2 mm. It would make the perfect gem for a unique engagement ring!
