This beautiful heated sapphire from the Rock Creek deposit in Montana is a gorgeous steely blue color. 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 excellent clarity; while there is one or two tiny inclusions visible in the macro image, they are not visible in the hand without a 10x loupe.
This sapphire is faceted in the classic diamond round brilliant design; the resulting gem is very bright and lively in the hand. It weighs 1.03 carats and measures 5.9 x 3.9 mm. It would make an amazing center stone for a beautiful engagement ring!
