Description
A rare 1969 specimen of bertrandite with beryl epigenium, found at Ménez Goaillou in Coray.
It comes from the mineral collection of F. Barillet (1898-2003), who was a chemical engineer and metallurgist for a major French company.
He traveled extensively throughout France as part of his profession and built up a systematic collection of several thousand samples, with a predilection for Brittany.
Handwritten label supplied.
