Wickenburgite, Willemite, Fluorite - AZ (Potter Cramer Mine)

Named after its discovery locality, the Potter-Cramer claim, near Wickenburg, Arizona, USA. One knowledgeable contributor comments: "This does not look like any Wickenburgite specimen I have ever seen. Looks more like Calcite from Hogan Claim in AZ" - we will look for another specimen to check the validity.
