A beautiful mint green unheated Montana sapphire faceted in my custom Helena brilliant oval design, 1.64 carats.

Out of stock


This Montana sapphire is a gorgeous mint green color, a light green with hints of blue, depending on the lighting.  Like nearly all unheated Montana sapphires, it shifts color depending on the lighting, appearing more greenish-blue under fluorescent lighting and a richer blue-green in daylight. The gem is very clean with only a slight amount of silk which only visible with a loupe.

I faceted this sapphire 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 1.64 carats and measures 6.8 x 5.9 x 4.7 mm.
