This beautiful unheated Montana sapphire is a unique combination of two colors, blue and green. The gem shows flashes of the two colors, creating a “particolored” effect. The gem is 100 percent natural and untreated in any way. The sapphire has excellent clarity, making it bright and scintillating in the hand. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
I faceted this sapphire in my custom “Hyperbola” brilliant oval design; the design is very bright and creates a beautiful pattern of scintillation in the hand. The sapphire weighs 2.08 carats and measures 8.0 x 6.9 x 5.0 mm; the perfect size for an engagement ring.
