Hi Don. I like your specimens. Please have a look at https://www.mindat.org/min-2379.html (link normalized by FMF) with regards to your Brandberg crystal with 'lepidocrocite' . Best regards.

Yes, nice Brandberg piece, but lepidocrocite has not been reported from this area, despite what the labels from many dealers say. These inclusions have been shown to be goethite or hematite. Changes made accordingly.

Thank you for your kind comment, Heimo. I enjoyed the pictures from your trip to the Namib Desert and particularly liked your Shattuckite specimens.

Don
