A beautiful medium blue heated Montana sapphire faceted in my custom “Testudo” brilliant oval design, 1.81 carats.

In stock


This gorgeous heated Montana sapphire is a bright medium blue–much brighter in person than the photo would imply.  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 and color.

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 1.81 carats and measures 7.7 x 5.9 x 4.9 mm.  It would make a lovely center stone for an engagement ring.
