This beautiful unheated Montana sapphire is a gorgeous robin’s egg blue, one of the finest shades of blue found in the Montana gems. The gem is 100 percent natural and untreated in any way. This sapphire appears to be nearly flawless. There are no visible inclusions, even when examined with a 10x loupe.
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 2.03 carats and measures 7.9 x 6.7 x 5.0 mm; the perfect size for an engagement ring.
