This gorgeous heated Montana sapphire is a unique combination of two colors, a rich teal blue, and a lighter green-blue. The colors are in zones, creating a bicolored effect. It has excellent clarity, with just a few tiny inclusions too small to see without a 10x loupe.
This sapphire is faceted in my custom “Stella” square cushion design. The gem weighs 1.56 carats and measures 6.5 x 4.3 mm. It would make an eye-catching center stone for an engagement ring.
