2.92-Carat Sky Blue Montana Sapphire

2.92-Carat Sky Blue Montana Sapphire


A beautiful sky blue unheated Montana sapphire in my custom Testudo brilliant oval design, 2.92 carats.

In stock


This lovely unheated Montana sapphire is a gorgeous sky blue color–a classic Montana sapphire color.  The sapphire has a moderate amount of inclusions, but they are much more difficult to see in person than the photo implies.  The gem is nearly eye clean in person, and has to be seen to be really appreciated.  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 2.92 carats and measures 9.2 x 7.0 x 5.8 mm.  This gem would make a beautiful center stone for a unique and one-of-a-kind engagement ring.
