In stock


This beautiful unheated Montana sapphire is a gorgeous violet to purple that changes color depending on the light. The gem is 100 percent natural and untreated in any way. This sapphire has slight inclusions that are just barely visible to the naked eye, and has a slightly hazy quality due to rutile silk. The inclusions have been factored into the price, making this a great value for the size and color.

This gem is faceted in a custom brilliant trillion design (a “trilliant”), modified and optimized for Montana sapphire.  The resulting gemstone is incredibly bright and scintillating in the hand.  The gem weighs 1.36 carats and measures 7.0 x 4.4 mm; it would an ideal stone for a unique engagement ring.
