Aerugite is a rare complex nickelarsenate mineral with a variably reported formula: Ni9(AsO4)2AsO6. It forms green to deep blue-green trigonal crystals. It has a Mohs hardness of 4 and a specific gravity of 5.85 to 5.95.

It was first described in 1858 in either the South Terres mine of Cornwall, England or in Erzgebirge, Saxony, Germany. The origin is disputed. The most common occurrence is as an incrustation on furnace walls in which ores are roasted. Its name comes from the Greek word aerugo for copper rust.

At every show I attend there are always some minerals available of exceptional rarity.
For starters at this show I have specimens of fettelite - a very rare silver/mercury arsenic sulfide and an unimaginably rare specimen of crystalline aerugite with crystals known from only one specimen that was subdivided into several.
There are others and there will be more as the show progresses.
