Description

This beautiful heated Montana sapphire is a classic color for the Montana gems–a bright blue-green.  The color was developed by heating the gem in Montana, but no other treatments were made to the gem.  The treatment is permanent and stable and not only develops the color, but also improves the clarity.  While the macro photo shows some zoning to the color, this is not very easily visible in the hand, as the facets blend the colors.  This gem is very clean, with only a small feather tucked off to one side, and not easily visible without a 10x loupe.  Its an eye clean gemstone and very bright and scintillating in the hand.

This sapphire is faceted in my custom “Helena” oval brilliant design that I’ve designed and optimized for sapphire; the result is a glittering beauty of a gemstone.  The gem weighs 4.83 carats and measures 10.7 x 8.9 x 6.7 mm.  This is very large for a Montana sapphire; each year I manage to get only a handful of sapphires large enough to create a finished gem this size.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
