A deep blue with hints of purple heated Montana sapphire faceted in my custom “Testudo” brilliant oval design, 1.09 carats.

In stock


This beautiful heated Montana sapphire is deep blue with hints of purple. The sapphire has moderate inclusions. 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 1.09 carats and measures 6.8 x 5.0 x 4.1 mm.  It would make a unique and interesting center stone for an engagement ring, at an affordable price.
