This remarkable unheated Montana sapphire is a wonderful shade of steely blue-green. 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-green, similar to how it appears in daylight.  While the macro image shows some internal inclusions, they are not easily visible in the hand without a loupe–face-up at normal viewing distance it’s an eye-clean gemstone.

I faceted this sapphire in a custom kite-shaped design that I created just for Montana sapphire.  I’ve named the design “Capella” in honor of a star in the constellation Auriga. The design is very bright and creates a beautiful pattern of scintillation in the hand.  This sapphire is large for a Montana sapphire: it weighs 3.10 carats and measures 9.2 x 7.6 x 6.1 mm.  Only a handful of sapphires are found in Montana each year that are large enough and clean enough to facet a gem of this size–making it a true collector’s item.
