A gorgeous deep blue heated Montana sapphire in my custom “Helena” brilliant oval design, 1.99 carats.

In stock


This beautiful heated Montana sapphire is a rich deep blue.  The color was developed by heating the gem in Montana, but no other treatments were made to the gem.  The treatment is permanent and stable and not only develops the color, but also improves the clarity.  The sapphire has outstanding clarity and is nearly flawless. It looks fantastic in person.

This sapphire is faceted in my custom “Helena” brilliant oval design that has been optimized for sapphire.  The gem weighs 1.99 carats and measures 7.9 x 6.8 x 4.9 mm.  Sapphires this large are very rare from Montana–it would make a superb center stone for a unique and one-of-a-kind engagement ring!
