Introduction: violarite is a rare mineral which may occur as a product of initial supergene alteration of nickel ores (Arnold & Malik, 1974), where it replaces pentlandite. Some hypogene occurrences are also known.

Occurrence in Wales: the occurrence of violarite from Wales is based on visual identifications in polished sections of siegenite from the Central Wales Orefield (Rust & Mason, 1988). The probable violarite occurs as grainy, poorly-polished replacements of the cobalt pentlandite lamellae that commonly occur in siegenite grains and which alter rapidly relative to the siegenite. It is purplish-brown in polished section. Confidence on this identification is only moderate (J.S. Mason, unpublished data), and therefore analytical confirmation is required. The paragenetic setting is, however, appropriate for the presence of violarite.
