Vial dated 1870 with light blue crusts from volcanic fumaroles. In the book "Mount Vesuvius" J. Logan Lobley states "At Vesuvius it is (aphthitalite) sublimed in delicate white crystallisations on the lava about the fumaroles and in the crater. It was
found both on the lava of 1868 and on that of 1872. Aphthitalite occurs at other volcanoes also." Aphthitalite was named in 1832 by Beudant. It is actually stable in air as the name implies, a derivative of the Greek word "unalterable". Aphthitalite was originally described from Vesuvius found as delicate crystallizations and in masses an inch or more thick (Dana 6th ed.). The material inside the vial can be seen as excellent thin tabular crystals.

This is an Azurite from the Easter Pocket on 8 level of the Tsumeb mine. There are two large tabular crystals, deep blue in color and mildly striated. The largest crystal is 3cm and the other prominent crystal is 2cm across. There are many smaller crystals. It is near perfect without damage except for detachment points of course. It is very lustrous and sits nicely without aid.
