1.18-Carat Pale Aqua Blue Montana Sapphire

1.18-Carat Pale Aqua Blue Montana Sapphire



A beautiful pale blue-green unheated Montana sapphire in my custom Testudo brilliant oval design, 1.18 carats.

In stock


This beautiful unheated Montana sapphire is a lovely pale blue-green color–similar to a lightly-colored aquamarine.  There are a number of small inclusions visible in the macro image, but they are almost impossible to see without a 10x loupe. In the hand it appears much better–it’s an eye clean gemstone.  I have factored the inclusions into the price, making this a great value for the size.

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 1.18 carats and measures 6.6 x 5.0 x 4.3 mm.  It would make a beautiful center stone for a unique and one-of-a-kind engagement ring.
