In stock


This beautiful unheated Montana sapphire is gorgeous aqua blue color, reminiscent of the color of a fine gem aquamarine.  There are some tiny rutile inclusions visible in the macro images but they are impossible to see in the hand without a 10x loupe–its an eye clean gemstone.  In the hand it is a very bright and scintillating gemstone.

I faceted this sapphire in a modified version of the classic diamond round brilliant design that I’ve optimized for sapphire; the result is a glittering beauty of a gemstone. The gem weighs 0.73 carats and measures 5.0 x 3.8 mm; the perfect size for an engagement ring.
