This beautiful unheated Montana sapphire is a unique combination of three colors, green, gold, and blue. The gem shows flashes of the three colors, creating a “parti-colored” effect. The gem is 100 percent natural and untreated in any way. The sapphire has excellent clarity. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
This sapphire is faceted in my custom oval brilliant design I created just for Montana sapphire. The design is called “Helena” in honor of the capital of Montana, located near the sapphire mines on the Missouri River in Montana. The gem weighs 4.37 carats and measures 10.4 x 8.7 x 6.4 mm. It would make a superb and unique center stone for an engagement ring.
