Yvonite is a hydrous copper arsenate. Sarp & Černý (1998) named the mineral after Professor Klaus Yvon (1943- ), crystallographer at the University of Geneva and innovator in hydrogen storage.

This is a rather rich example of yvonite, forming a blue crust along the 5.6 cm length of specimen. Associated is blue-green pushcharovskite, all on a matrix of bismuth and löllingite. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. An earlier Gilbert Gauthier label accompanies the specimen.
