This beautiful heated Montana sapphire is a gorgeous rich peacock blue–a shade of deep blue tinted with green that reminds me of the feathers of a peacock. 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 some tiny inclusions that are not visible without a loupe; it’s an eye-clean gemstone.
This sapphire is faceted a custom brilliant oval design that has been optimized for sapphire. The gem weighs 2.23 carats and measures 8.3 x 6.8 x 5.1 mm. It would make an eye-catching center stone for a one-of-a-kind engagement ring.
