0.86-Carat Pale Blue Montana Sapphire

0.86-Carat Pale Blue Montana Sapphire


A beautiful pale blue-green unheated Montana sapphire in my custom Testudo brilliant oval design, 0.86 carats.

In stock


This lovely unheated Montana sapphire is a pale blue-green color, a classic color for the Montana sapphires.  The gem is extremely clean, with just one tiny inclusion only visible with a 10x loupe.  The high clarity makes this gem very bright and scintillating in the hand.

This sapphire is faceted in my custom “Testudo” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 0.86 carats and measures 6.2 x 4.7 x 3.8 mm.  This gem would make a beautiful center stone for a unique and one-of-a-kind engagement ring.
