Type Locality 

Powdery yellow mineral in vial dated 1924. I am not sure if that is when it was collected or if it is from an eruption in 1924. It a relatively new vial, so not an antique like the other vials. Vesuvius is the type locality for Palmierite. Palmierite is rare having been reported from only nine localities worldwide.

Antique Specimen 

This so-called chloride of iron is rather uncommon and is usually found in salt deposits. It has been grandfathered as a species, since it was described prior to 1959. As you can see, the antique specimen vial dates to 1926. The specimen itself is 1.5 x 1cm and has a pale yellow fibrous appearance in layers and perhaps a little copper mineralization as noted by the blue colors on the surface. It's a valuable specimen since it is so old and may be one of the original specimens.
