Superior Country has an abundance of purple-hue quartz – Amethyst. This gemstone is the official mineral of Ontario. Amethyst formed in the fault lines 1.1 billion years ago, during the mid-continent rift. The crystallization of the hot water and the mineral deposits along the fault line created the amethyst we find today. Ontario’s jewel can become your own as you dig, uncover, and clean your very own piece at one of the many mines in Ontario’s Superior Country.
