In stock


This beautiful unheated Montana sapphire is a lovely aqua blue color–reminiscent of the color of a gem aquamarine.  It has a very slight amount of natural rutile silk just barely visible in the image, but its not visible in the hand without a 10x loupe.  In the hand this is stunning gem, with great bright color and beautiful brilliance.

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 1.17 carats and measures 6.2 x 4.1 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
