1.76-Carat Teal Blue Montana Sapphire

A beautiful teal blue unheated Montana sapphire faceted in my custom Testudo brilliant oval design, 1.76 carats.

In stock


This beautiful unheated Montana sapphire is a gorgeous teal blue-green color.  While the macro image shows a slight color zone, this is only barely visible in the hand.  The gem has excellent clarity, with just a minor amount of rutile silk, only visible with a 10x loupe.  The high clarity makes this gem remarkably bright and scintillating in the hand.

This sapphire is faceted in my custom “Testudo” oval brilliant design. The gem weighs 1.76 carats and measures 7.8 x 5.9 x 4.9 mm.  It would make a superb center stone for an engagement ring.
