Out of stock


This beautiful heated Montana sapphire is a gorgeous combination of aqua and blue. The gem shows flashes of the two colors, creating a “particolored” effect. 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 sapphire appears to be nearly flawless. There are no visible inclusions, even when examined with a 10x loupe.

This gem is faceted in our custom “Helena” brilliant oval design, created and optimized for sapphires; the result is a glittering beauty of a gemstone. The gem weighs 1.35 carats and measures 7.0 mm x 5.9 mm x 4.4 mm.
