Field-hunting tip
Look in mollusk shells country — that is the host setting where gold pearl typically forms. If you start seeing aragonite, calcite in float, you are in the right ground. Field specimens usually show a spherical habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Iowa — start trip planning there.
