1.0ct Missouri River Sapphire, Unheated
5.7mm, Custom USA cutting by Christopher Bork
A classic Silvery Blue Montana Sapphire from the gravel deposits along the Missouri River outside Helena, MT. Stunning precision cutting brings out the most in this lively Sapphire. The Powder Blue color holds under any lighting, unusual for a Montana Sapphire. There is a small inclusion visible only under magnification, and some very light silk, just enough to soften the brilliance a bit. Great size for a Sapphire engagement ring!
