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.
