Description
Old specimen of Huelgoat bromyrite crystals, collected in the early 19th century, from the Chervet collection and therefore quite rare today. Well preserved, no rubbing and showing good crystals. In short, a good historical piece.
The Huelgoat silver mine is located in the Finistère department of Brittany.
Bromyrite or bromargyrite is a silver bromide with traces of chlorine and iodine.
