Montana’s only true precious gemstone mined today are sapphires. Throughout history sapphires were the jewels of choice for the crowns of all European royal families. These beautiful, all natural sapphires are mined from the Eldorado Bar sapphire deposit located off of the Missouri River in Helena Montana. Our sapphires come in a rainbow of colors including natural color-changers. We offer to you, direct from the mine, faceted Montana sapphires, cutting rough, and bags of sapphire gravel. The all natural Montana sapphire is your opportunity to own a “piece of Montana”, the Treasure State.
