A superb, rich blue heated Montana sapphire faceted in my custom “Testudo” brilliant oval design, 1.08 carats.

In stock


This beautiful heated Montana sapphire is a superb, rich blue–one of the most desirable shades of blue to be found in the Montana sapphires. It has excellent clarity, with only one or two tiny inclusions only visible with a 10x loupe.  

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 1.08 carats and measures 6.6 x 4.9 x 4.1 mm.  It would make a gorgeous center stone for an engagement ring.
