This beautiful heated Montana sapphire is a cornflower blue–one of the most desirable hues for a sapphire. 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 small inclusions that are quite difficult to see with the naked eye from a normal viewing distance. The inclusion is in a corner where it can be hidden under a prong when the gem is set.
This sapphire is faceted in a modified version of the classic diamond round brilliant design that is optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 1.01 carats and measures 6.0 x 3.9 mm; the perfect size for an engagement ring.
