1.91ct Unheated Missouri River Sapphire, El Dorado Bar Mine, Montana
Cut by Bob Sivinski in Jeff Graham’s “Nigerian Cushion”
7.29 x 7.1 x 4.95 mm
A light icy blue outdoors, and nearly colorless indoors. This gem’s brilliance and clarity is truly outstanding, the small inclusions are invisible in hand, however some do reach the surface around one corner of the girdle, and should be avoided during setting. Even better in person than the pictures imply, this would make a smashing engagement ring.
