System:Trigonal
Member of:Atacamite Group
Name:Named after Christo Kapellas (1938-2004), collector and mineral dealer of Kamariza, Lavrion, Greece.
Isostructural with:Haydeeite


Atacamite Group.
A metastable polymorph of Herbertsmithite. Has been confused with Botallackite ("Zn-bearing botallackite"; Wendel et al., 1999); both are visually very similar.
Also known as a synthetic compound (phase IIα of Feitknecht and Maget, 1949).

The Mg analogue of kapellasite is called haydeeite.
