This lovely heated Montana sapphire is a beautiful medium blue-green color, reminiscent of a fine gem aquamarine. The sapphire was heated in Montana to develop the color and improve the clarity; the treatment is permanent and stable. This gem has good clarity, with just one small inclusion, but it’s tucked off to the edge where it can be hidden under a prong when set.
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 1.05 carats and measures 6.0 x 3.8 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
