About the Program: Amethyst Deposits of Thunder Bay, Ontario: Presented by Dick and Mary Pat Weber

The largest commercial deposits of amethyst in North America occur near the Canadian border in Southern Ontario. Unlike the more common Brazilian amethyst, this material is unique due to inclusions of red hematite in the outermost layers of the crystals. Dick Weber first visited these deposits in the 1970s while studying for his graduate degree in Geology at the University of MN, Duluth.
