0.94-Carat Colorless Montana Sapphire

0.94-Carat Colorless Montana Sapphire



A beautiful colorless unheated Montana sapphire in my custom Helena brilliant oval design, 0.94 carats.

In stock


This beautiful unheated Montana sapphire is completely colorless.  It has a very slight amount of natural rutile silk that is just visible in the macro image, but its not visible in the hand without a 10x loupe.  In person its a brilliant and scintillating gemstone.

This sapphire is faceted in my custom “Helena” oval brilliant design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 0.94 carats and measures 6.1 x 5.1 x 3.8 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
