Catalog Search Guide
You can search our catalog using different mineral attributes. For example, you can search by color such as green, yellow or purple, or by chemical elements such as uranium, calcium or iron, or by mineral groups such as phosphate, silicate or carbonate. You can also filter by crystal habit like crystal, geode or crystal on matrix, by specimen size such as thumbnail, small, medium or cabinet, and by features such as radioactive or fluorescent minerals.
Campania
Campania, in southern Italy, is defined mineralogically by one of the world's most celebrated volcanic districts: the Somma-Vesuvius Complex overlooking the Bay of Naples, together with the fumarolic fields of the Campi Flegrei and Solfatara di Pozzuoli. Centuries of eruptive activity, from the Plinian event of 79 AD onward, ejected countless skarn and sanidinite xenoliths rich in exotic mineral associations, making this small region a cornerstone of classical European mineralogy. Mount Vesuvius alone stands as the type locality for over forty valid mineral species, a record that places Campania among the most scientifically important collecting regions on Earth.
The volcanic ejecta of Monte Somma and Vesuvius have yielded superb crystals of vesuvianite (idocrase), first described from this very locality, alongside leucite, humite, sanidine, phlogopite mica, hauyne, nosean, sodalite, meionite, wollastonite and lustrous andradite garnet. Quarries such as San Vito in Ercolano and the Trapolino Quarry in Somma Vesuviana are renowned among collectors for gem-quality micro-crystals extracted from calc-silicate blocks. The volcano is equally famous for its distinctive coralloid, twinned aragonite and for a suite of rare fumarolic species, including copper minerals such as malachite, while the sulfur-rich vents of Pozzuoli and the wider Campi Flegrei caldera continue to produce native sulfur and alunite in active solfataric conditions.
Collectors prize Campanian specimens for their unique link to the birth of modern mineralogy: many species named from Vesuvius material were first studied and catalogued in the historic Royal Mineralogical Museum of Naples, giving these pieces both scientific pedigree and cultural weight. The sharp, well-formed habit of crystals grown in volcanic cavities, combined with the sheer diversity of an active magmatic-hydrothermal system, means specimens from Naples, Vesuvius and the surrounding Campania volcanic province remain highly sought after by systematic collectors, museums and anyone drawn to minerals with a documented, storied provenance from one of the most studied volcanoes in the world.
