In stock


This beautiful unheated Montana sapphire is a gorgeous rich aqua blue color, similar to a fine gem aquamarine.  While the macro image shows some light rutile silk, its not visible without a 10x loupe and in the hand its a beautiful and bright gemstone.

This sapphire is faceted in my modified version of the diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” level of precision; the result is a glittering beauty of a gemstone.  The gem weighs 0.61 carats and measures 5.1 x 3.3 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
