This beautiful heated Montana sapphire is a gorgeous robin’s egg blue, one of the finest shades of blue found in the Montana gems. 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. The sapphire has excellent clarity, making it bright and scintillating in the hand. There may be tiny inclusions that are visible with a 10x loupe that are difficult or impossible to see with the naked eye at a normal viewing distance.
This sapphire is faceted in our custom “Eureka” brilliant rectangle cushion design, created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 1.08 carats and measures 6.4 x 4.8 x 4.1 mm; the perfect size for an engagement ring.
