This gorgeous heated Montana sapphire is a lovely sky blue color. The sapphire has a few tiny crystal inclusions that are not visible without a 10x loupe; it’s an eye-clean gemstone.
This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 0.85 carats and measures 6.2 x 4.6 x 3.7 mm. It would make a unique and eye-catching center stone for an engagement ring.
