Binghamite, also known as "silkstone" or "cuyunite", is a highly sought after variety of agate that is only found near the Cuyuna iron range in Crow Wing County, Minnesota. It often displays vibrant red, orange, and yellow colors and in some cases contains small veins of iron running throughout the agate. Many specimens have chatoyant properties that are similar to tiger's eye. The chatoyance can be attributed to the fibrous hematite and goethite parallel crystal formations that the agate deposits around.
