A large and fine example of a particularly unusual combination of Marcasite with Chalcedony from the collecting area around Nipomo, California. Many decades ago this was an accessible rockhounding area, but now it has been restricted for many years. The patterning of the Marcasite is quite distinctive and its combination with semi-translucent Chalcedony (this material is sometimes called Marcasite Agate) is quite unique. From an older cab collection and a one-off example for us.
