This gorgeous Montana sapphire is completely colorless, a relatively rare find for the Montana sapphires. Completely natural and untreated, this is the color of the gem just as it formed deep in the earth, millions of years ago. This sapphire has excellent clarity, with just a tiny amount of natural rutile “silk” only visible with a 10x loupe. Unheated natural sapphires with excellent clarity like this are quite rare; each year we are only able to cut about 5-7% of our rough without having it heated. Color-change sapphires like this one are rare; each year we mine only a handful at our mine in Montana.
This gem is faceted in our custom “Helena” brilliant oval design, created and optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 0.36 carats and measures 4.6 mm x 4.0 mm x 2.8 mm.
