Pronunciation: [kˈampɪɡlɪˌa͡ɪt] (IPA) 
Campigliaite is a rare mineral named after the town of Campiglia in Italy, where it was first discovered. The word can be broken down phonetically as /kæmˈpɪliˌdʒaɪt/. The "c" is pronounced as a hard "k" sound, and the "g" is a soft "j" sound. The emphasis is on the second syllable and the "i" is pronounced as a long "ee" sound. The ending "-ite" is common in mineral names, indicating that it is a type of mineral.
Campigliaite is a rare mineral that belongs to the mineral class of sulfates. It is named after its type locality, Campiglia Marittima, Italy, where it was first discovered. Campigliaite is characterized by its distinct crystal habit, often appearing in formless, fibrous, or powdery masses. It has a vitreous to resinous luster and commonly occurs as transparent to translucent crystals.
Chemically, campigliaite is a copper sulfate mineral with the chemical formula Cu4(SO4)(OH)6·2H2O. It typically forms as a secondary mineral, resulting from the oxidation of primary copper sulfide minerals under specific environmental conditions. Campigliaite often occurs in association with other copper minerals, such as chalcanthite and brochantite.
The physical properties of campigliaite include a light blue to greenish-blue color, as well as a pale blue streak. Its hardness ranges between 2.5 and 3 on the Mohs scale, indicating a relatively soft mineral. It also has poor cleavage and a brittle tenacity.
Though campigliaite is primarily found in Italy, it has also been reported in other countries such as England, Australia, and the United States. Due to its scarcity and limited occurrence, campigliaite is highly sought after by mineral collectors and researchers studying mineral formations. Its unique crystal structure and color make campigliaite an aesthetically pleasing and valuable addition to any mineral collection.
