In stock


This beautiful Montana sapphire is a wonderful steely blue-green color in daylight and under fluorescent light.  Under incandescent light, however, it changes to a beautiful steely lavender purple.  The effect is very difficult to photograph, so it has to be seen in person to be fully appreciated.  The gem has outstanding natural clarity, with no visible silk and just one tiny veil tucked off near an edge, where it’s almost impossible to see without a loupe.  The high clarity makes this gem very bright and scintillating in the hand.

This sapphire is faceted in my custom oval brilliant design I created just for Montana sapphire.  The design is called “Helena” in honor of the capital of Montana, located near the sapphire mines on the Missouri River in Montana. The gem weighs 2.07 carats and measures 7.8 x 6.7 x 5.1 mm.
