A lovely sky blue unheated Montana sapphire, 0.64 carats.

In stock


This lovely unheated Montana sapphire is gorgeous sky blue color, like the “big skies” of Montana. The gem has just a slight amount of natural rutile silk that just slightly softens the brilliance of gem, and a few tiny crystal inclusions only visible with a 10x loupe–in the hand it’s an eye-clean gemstone.

This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 0.64 carats and measures 5.0 x 3.3 mm; the perfect size for an engagement ring.
