This beautiful heated Montana sapphire is a beautiful deep royal blue color–an uncommon shade of blue for the Montana gems. The gem has good clarity, with just a few tiny inclusions too small to see without a loupe; it’s an eye-clean gemstone.

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 0.73 carats and measures 5.8 x 4.6 x 3.7 mm.  It would make a unique and eye-catching center stone for an engagement ring.
