Description

This beautiful heated Montana sapphire is a rarity–a color-change sapphire.  In daylight and some fluorescent lights it appears a steely blue color, with faint hints of purple, while under incandescent light, it changes to a beautiful purple color.  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.  This gem has very good clarity, with just a few tiny inclusions not visible without a 10x loupe.  Its very brilliant in the hand!

This sapphire is faceted in my modified version of the classic diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” precision.  The gem weighs 1.14 carats and measures 6.2 x 4.1 mm.  It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
