This specimen is a very rare find as Crocoite needs an acidic environment to develop, and Cerussite is a carbonate, that usually will dissolve in an acidic environment. This specimen proofs a change of chemical composition of the environmental circumstances around the Red Lead Mine in Tasmania and therefore scarce. Only a few specimen were extracted. This is the best available.


A very special one is this Cerussite. A pseudo hexagonal (due to twinning), lemon-yellow 10 x 5 mm crystal. Note the crocoite spray on one corner. It's an absolute rare find from the Red Lead Mine, Dundas, Tasmania.

On this specimen there are several lead minerals present. Anglesite with grimaldiite. Whole specimen is 90 x 60 x 40 mm. Weight 593 grams.



Crocoite
is a unique mineral recognized as a lead chromate (PbCrO4). Its striking orange-red hue and remarkable crystal structures, typically found in prismatic shapes or granular forms, make it particularly notable. As a member of the chromate mineral group, crocoite attracts collectors due to its vivid coloration and distinct look. With a Mohs hardness rating of 2.5 to 3, it is considered relatively soft and delicate.

Cerussite, also referred to as lead carbonate or white lead ore, is a mineral characterized by its chemical composition of lead carbonate (PbCO3) and serves as a significant source of lead. The term derives from the Latin word "cerussa," meaning white lead. Historical references to the mineral date back to 1565 when Conrad Gessner mentioned "cerussa nativa." In 1832, F. S. Beudant introduced the name "céruse," while the current designation, cerussite, was established by W. Haidinger in 1845. Early miners commonly referred to it as lead-spar or white-lead-ore.
