About Berryite
Formula:
Cu3Ag2Pb3Bi7S16
Formely considered to be Pb3(Ag,Cu)5Bi7S16.
Colour:
Bluish-grey, white, grey-white
Lustre:
Metallic
Hardness:
3½
Specific Gravity:
6.7
Crystal System:
Monoclinic
Name:
Named in honor of Leonard Gascoigne Berry (1914-1982), Canadian mineralogist, Professor of Mineralogy and Crystallography at Queen’s University, Kingston, Ontario (1945-1979), who first investigated the mineral from the Swedish type locality (TL2), in 1939. Berry was the founding editor of The Canadian Mineralogist (1957-1975).
An orthorhombic polytypic variant has been postulated (Topa et al., 2006).
Structurally related to litochlebite and watkinsonite.
Visually similar to emplectite and several other sulphosalts.
