This beautiful all-natural Montana sapphire is a gorgeous medium sky blue color; one of my favorite colors found in Montana sapphires. Like most unheated Montana sapphires, the color shifts depending on the lighting, shifting more towards a blue-green in daylight and some LED lights while appearing a more bright silvery blue indoors under incandescent lighting.
The gem has a light amount of rutile silk and one small crystal inclusion, but they are not visible without a loupe. I faceted this sapphire in a brilliant oval design that I’ve optimized for sapphire. I call the design “Testudo” as the facet pattern on the crown reminds me of a tortoise’s shell. The gem weighs 1.33 carats and measures 6.6 x 5.0 x 4.7 mm; the perfect size for an engagement ring.
