WOW!!! What a superb Kelly mine smithsonite featuring incredible colour and shape! A mineral ore of zinc. Historically, smithsonite was identified with hemimorphite before it was realized that they were two different minerals. The two minerals are very similar in appearance and the term calamine has been used for both, leading to some confusion.
