4.57ct Round Unheated Montana Sapphire
$8,000.00
4.57ct Round Montana Sapphire, Unheated, from the Missouri River Deposits
8.6 x 7.4mm
Custom cut in the USA by Daniel O’Neil, in a design hand-drawn just for this Montana Sapphire! A refreshing Aqua Blue color, with lots of interesting scintillation. As with many Montana’s, there is some light rutile silk in this gem, enough to give it a soft glow as opposed to a hard brilliance (and also proof that it is completely unheated/untreated). Only a few Montana Sapphires this size are recovered in a mining season by the small, family-owned mines working the banks of the Missouri River outside Helena, MT. A truly rare American Treasure!
Comes with an AGL report stating Unheated Natural Sapphire.
