This lovely heated Montana sapphire is an unusual pale yellow-green color, although in most lighting the pale yellow hue predominates. The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. This gem has very good clarity, with just a few tiny inclusions only visible with a 10x loupe.
This sapphire is faceted in the classic diamond round brilliant design that has been specifically optimized for sapphire and cut to “hearts and arrows” precision; the result is a glittering beauty of a gemstone. The gem weighs 1.67 carats and measures 7.0 x 4.6 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
