In stock


This beautiful heated Montana sapphire is a gorgeous aqua blue, bringing to mind the tropical waters of the Caribbean Sea. 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 has very slight inclusions that are just barely visible to the naked eye. The inclusions have been factored into the price, making this a great value for the size and color.

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 0.46 carats and measures 4.8 x 3.7 x 3.0 mm; the perfect size for an engagement ring.
