BINGHAMITE AGATE FOR SALE

Binghamite, also known as "silkstone" or "cuyunite", is a highly sought after variety of agate that is only known to come from one location in Minnesota. This agate formation is found near the Cuyuna iron range in Crow Wing County, Minnesota. It often displays vibrant colors of red, orange and yellow 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.
