About Us
Welcome to Michigan Rocks & Minerals website. My name is Cory Cotter, an educator-entrepreneur, founder of Michigan Rocks & Minerals.
I sell museum-quality specimens from around the world, specializing in Michigan Rocks & Minerals. I sell quality, not quantity. I have published several articles, including a Little Big History of Amethyst Geodes, written during the course of my postdoctoral studies at the University of Michigan.
I am currently working on a history of Michigan Copper, focusing on the Keweenaw Peninsula.
