This beautiful heated Montana sapphire is a gorgeous midnight blue. 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 may have tiny inclusions that are visible only with a 10x loupe. There is a slight haze to the gem from undissolved rutile silk, but it gives the gem a soft glow that is quite pleasing and enhances the color in low light. The inclusions and haze have been factored 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 2.75 carats and measures 8.4 x 5.5 mm; the perfect size for an engagement ring.
