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 faded blue-jeans 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!
