This spectacular heated Montana sapphire is a deep peacock blue–a deep blue with a faint tint of green. 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. This gem has some minor inclusions, but they are not visible in the hand without a 10x loupe–its an eye clean gemstone.
This sapphire is faceted in my modified version of the classic diamond round brilliant cut, optimized for sapphire and cut to “hearts and arrows” precision. The gem weighs 1.74 carats and measures 7.0 x 4.7 mm. It would make an amazing center stone for a unique and one-of-a-kind engagement ring.
