A beautiful teal blue heated Montana sapphire faceted in my custom “Testudo” brilliant oval design, 1.18 carats.

In stock


This beautiful heated Montana sapphire is a bright teal blue with flashes of green, a classic Montana sapphire color. The sapphire has good clarity, but does have one slight inclusion that is just barely visible in hand.  I have factored this into the pricing, making it a good value for the size.

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 1.18 carats and measures 6.8 x 5.2 x 4.2 mm.  It would make a gorgeous center stone for an engagement ring.
