We find them literally everywhere on my parents property (Western Wisconsin, United States) and I'm curious to know what they are called. The crystals vary from a very pale brown, almost white, to a very dark reddish brown. But they are always consistent in size, very small. The photos do not do them justice. They are absolutely gorgeous in person.
