It crystallizes in the triclinic crystal system (space group P1). It is a member of the Cyanotrichite structural group.
Key properties: specific gravity 3.1; Pale green streak; Silky luster; optically biaxial.
IMA symbol Cmé, IMA status: approved, named in 1990.
A rare secondary mineral found in the oxidized zone of polymetallic mineral deposits.
It is found associated with Parnauite, cyanotrichite, malachite, quartz (Cap Garonne mine, France); brochantite, chalcophyllite, mimetite, azurite (St.-Luc, Switzerland).
The mineral was named to honor Michel Camerola, mineral collector who collected the first specimen.
