Dundasite pseudomorph after Cerussite (RARE locality specimen!) (ex Dr. Wouter van Tichelen Collection)

Item Description

An INCREDIBLY hard to find specimen for the simple fact that not only is it from Ireland, where it's rather difficult to get your hands on any orebody specimens, but this is honestly the ONLY specimen of this particular pseudomorph from this locality that we've had to offer. The piece features semi-"spray"-like groups or "jackstraw"-esque formations consisting of thin prismatic crystals of Cerussite which have pseudomorph into soft greenish-yellow Dundasite on host rock matrix. The piece is beautiful up close, and fun to view with a loupe or under the microscope. This locality is a very large polymetallic deposit rich in zinc, copper and lead ore which was actually oxidized into minerals such as Azurite, Malachite and Cerussite, which were high quality (museum grade according to the listing on mindat.org). If you look at specimens online, they remind one of similar pieces from Arizona or Tsumeb in terms of quality and form. Unfortunately the vast majority of the specimens met their fate in the crusher, so little remained for collectors. It is still a very noteworthy locality as nearly 100 species have been reported, and are sought after by collectors, as the locality has been closed since 1982. I value this highly (around $1,000) in terms of its rarity both mineralogically and in terms of the locality. From the noted pseudomorph collection of Dr. Wouter van Tichelen of Belgium.
