1.7ct Montana Sapphire, Unheated
1.71ct Unheated Montana Sapphire, Missouri River Valley Deposit
6.35 x 6.35 x 4.7 mm, Precision Cut in Arizona by Ex Lapidus
A classic color shifting Montana Sapphire, from Aquamarine color to River Green, and every shade in between! 100% Unheated/Untreated, and sustainably mined by a small family owned operation along the banks of the Missouri River in Montana. Outstanding American cutting by Christopher Bork, in our favorite square pattern – Marco Voltolini’s “Squaretugese” design. There are a few small inclusions in this one, but they are difficult to see at arm’s length.
