Nodules. I didn't really understand until recently where these nodules came from. People in China are selling bunches of them, and they are very beautiful. I thought they must be electrowinning nodules (built up by electroplating), considering how similar they look to the nickel and copper electrowinning nodules I have. Fortunately reader Eric Winter has kindly pointed me to this article which indicates they are probably vapor deposited in the "Pidgeon process".
