This gorgeous heated Montana sapphire is an unusual and lovely mint green. The sapphire has 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 6.3 x 4.8 x 3.7 mm. It would make a unique and eye-catching center stone for an engagement ring.
