JFD212AP6: Anglesites pseudomorphed by Cerussite and covered with Goethite are a Spanish classic from the San Valentín Quarry, but this particular piece is different, both for not being covered with Goethite and for its intense yellow color and the dissolution figures in some crystals.
Curiously I bought it in France. It was from Alain Martaud's collection (with a label) and he must have bought it from Maurice Boudon, a French engineer who worked at La Unión.
