A lovely pale blue-green unheated Montana sapphire in my custom “Testudo” oval design, 1.51 carats.

In stock


This lovely unheated Montana sapphire is a beautiful pale blue-green color–so pale that it can appear colorless in some lighting.  There are a few tiny inclusionsvisible in the macro image, but they are impossible to see in the hand without a 10x loupe.  It is very clean otherwise, making a very bright and scintillating gemstone in the hand!

This sapphire is faceted in a custom brilliant oval design that I created just for Montana sapphire. I’ve named the design “Testudo” as the facet pattern of the crown reminds me of a tortoise’s shell.  The gem weighs 1.51 carats and measures 7.3 x 5.4 x 4.7 mm.  It would make the perfect gem for a unique engagement ring!
