Lanarkite is certainly one of the rarest species from the Leadhills area, Scotland. The specimen we have is from the areas most well known location at the Susanna Mine. Classically formed bladed terminated crystals of Lanarkite measuring to 6mm are seen grown in from both sides of the specimen, associated with platy crystals of creamy-yellowish Leadhillite. Crystals of Lanarkite are colourless to mostly tinted blue, with some associated Caledonite. The outside of the specimen displays the typical white Cerussite with a partial yellow-orange Pyromorphite cover. A classic specimen from the mine.
