This beautiful heated Montana sapphire is a unique combination of two colors, yellow and blue. The gem shows flashes of the two colors, creating a “parti-colored” effect. The blue is more visible in person. 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 slight inclusions that are just barely visible to the naked eye. I have factored the inclusions into the price, making this a great value for the size and color.
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 1.30 carats and measures 6.4 x 4.2 mm; the perfect size for an engagement ring.
