1.91ct Montana Sapphire Cabochon, 100% natural and untreated, El Dorado Bar Mine
Cut by Brett Kosnar
6.1 x 5.9 mm
A delicate silvery sky blue Montana with excellent clarity, cut here in the USA with a generous high dome and outstanding polish. Cabbed Montana sapphires are difficult to come by, especially with such crystal clarity! A few small feather inclusion reach the surface one one side, not normally visible in hand. Under a 10x loupe, some black spinel crystals and a very small amount of silk show.
