3.27-Carat Blue-Green Montana Sapphire


A beautiful blue-green unheated Montana sapphire in a custom square cushion design, 3.27 carats.

In stock


This beautiful unheated Montana sapphire is a gorgeous bright blue-green to teal color–a classic Montana sapphire color.  There is a very light amount of natural rutile silk in this sapphire (proof of its natural unheated status) but its only visible at certain angles and it doesn’t effect the brilliance of the gem in any way.  It is a beautiful eye clean gemstone, and quite large for Montana.

This sapphire is faceted in my custom “Bella” brilliant square cushion design that I’ve created and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 3.27 carats and measures 7.8 x 5.8 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
