Paralaurionite is a rare lead species usually occurring as microcrystals. However there was once a find here which redefined, by an order of magnitude, one's expectations. This is from that find, an important specimen with huge crystals for the species. This piece could be considered one of the world's great specimens for the species and resided in a pre-eminent collection including many other such rarities (John Barlow's). Illustrated in the F John Barlow Collection book.
