This pretty little unheated Montana sapphire is a lovely shade of light blue-green, reminiscent of the color of an aquamarine. Like nearly all unheated Montana sapphires, the color will shift with the lighting: Under incandescent light it looks more silvery-blue, while under fluorescent the color appears a richer blue with a tint of green, similar to how it appears in daylight. While the macro image shows some silk, it is not not nearly as prominent in the hand. When held in the hand the silk gives just a slight softening to the natural brilliance of the gem.
I faceted this sapphire in a custom oval design that I created just for Montana sapphire. I’ve named the design “Helena” in honor of the capital of Montana, located just a few miles from the famed sapphire deposits of the El Dorado Bar on the Missouri River, where this sapphire came from. The design is very bright and creates a beautiful pattern of scintillation in the hand. This sapphire the perfect size for a unique engagement ring: it weighs 1.40 carats and measures 6.7 x 5.7 x 4.5 mm.
