Montana’s wealth of gem deposits has earned it the nickname “The Treasure State”, and chief among its bounty is the magnificent sapphire. Most Montana sapphires recovered in the 1800s were destined for industrial use.

Join GIA researchers Aaron Palke and Nathan Renfro as they unearth the history, geology and gemmology of these stunning jewels
