A beautiful light blue-green unheated Montana sapphire in a classic emerald cut, 0.85 carats.

In stock


This lovely unheated Montana sapphire is a classic color for the Montana gems–a light blue-green. It is completely natural and unheated, and has just a tiny amount of microscopic rutile silk to prove its unheated state.  It is exceptionally clean for an unheated sapphire, and very bright and scintillating in the hand.

This sapphire is faceted in the classic emerald cut, optimized for sapphire and cut to high precision.  The gem weighs 0.85 carats and measures 6.1 x 4.5 x 3.0 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
