2.72-Carat Medium Blue-Green Montana Sapphire


A beautiful blue-green unheated Montana sapphire in my “Bella” custom square cushion design, fairly large for Montana at 2.72 carats.

Out of stock


This gorgeous unheated Montana sapphire is a classic Montana color–a beautiful medium blue-green color.  The sapphire has very high clarity, with just a few tiny inclusions only visible with a 10x loupe.  There is a very light amount of extremely fine rutile silk that imparts a very slight glow to the gem–a beautiful visual effect.

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 2.72 carats and measures 7.1 x 5.5 mm–fairly large for a Montana sapphire.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
