Description

This is a special small specimen: yellowish orange cacoxenite on a limonitic matrix forms a nice but unspectacular example. The interesting fact is that it comes from the type locality and with a label of the notorious Charles Ottley Groom-Napier (Museum M&M) which dates it into the second half of the 19th century.
