This beautiful heated Montana sapphire is a gorgeous teal blue color, one of my favorite shades of blue found in the Montana sapphires. The color was developed by having the sapphire heated in Montana–but that is the only treatment it has had. The heating not only deepened the color, but it also improved the clarity–the gem is bright and lively in the hand. The gem has extremely high clarity, with only one tiny crystal inclusion, only visible with a 10x loupe.
This sapphire has been faceted in a modified version of the classic round brilliant design, optimized for sapphire and cut to “hearts and arrows” precision. The result is a sparkling gem weighing 1.07 carats and measuring 5.9 x 3.9 mm. This would make a lovely center stone for an engagement ring.
