An excellent specimen for the species. It is a tabular crystal with striations and bronze iridescence. The needles are apparently Zinkenite and there are also tiny yellow crystals which look like sulfur, but may be Cervantite. Rob Lavinsky has an excellent write-up about these Andorites and their occurence on Mindat to which I got some of this information. Click here to see it.
