4.57ct Round cut Montana Sapphire, Unheated, from the Missouri River Deposits
8.6 x 7.4mm
Fabulous Designer Cut performed in the USA by Daniel O’Neil, in a special design he drew just for this Montana Sapphire! A refreshing Aqua Blue color, with lots of interesting scintillation. As with most Montana’s, there is silk in this gem, enough to give it a soft glow as opposed to a hard brilliance. It would be an excellent candidate for heat treatment, but in this case we love it so much as-is we’ve decided to offer it up in it’s natural earth-mined state.
