Thunderegg-Adjacent Stones

Stones that are either related to thunderegg or look similar to thundereggs, yet aren't. Or aren't quite. These are provided for comparison purposes and because they are also very beautiful and remarkable. Also, there is nothing comprehensive about these - this is just a repository for stones that I happened to acquire. Sometimes I know what they are - sometimes I don't.
