A beautiful blue-green unheated Montana sapphire in a custom oval design, 1.06 carats.

In stock


This beautiful unheated Montana sapphire is a lovely blue-green color–a classic Montana sapphire color. This gem has excellent clarity, with a light amount of rutile silk that is only visible with a 10x loupe.

This sapphire is faceted in a custom version of my “Helena” brilliant oval design, optimized for sapphire and cut to high precision.  It weighs 1.06 carats and measures 6.8 x 5.3 x 3.8 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
