This beautiful unheated Montana sapphire is a unique combination of two colors, blue and yellow. 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. A slight haze from rutile silk is visible in the photo but not visible 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 6.8 x 5.0 mm; the perfect size for an engagement ring.
