Leadhillite (ex Brian Kosnar Collection)

Item Description

A hard to find, attractive thumbnail specimen of pale blue colored monoclinic Leadhille with whitish-silver Cerussite, but stark blue gemmy crystals of what could very possibly Boleite since they do appear to be cubic in habit, and the association with Leadhillite has been reported from this locality. Tiger is world famous for its colorful secondary ore minerals, and pieces like this are nearly impossible to find on the open market. They are only found in old collections.
