Very rich specimen formed by numerous prismatic crystals of wulfenite, with orange color zoning. They are brilliant and disposed very aerially on the matrix. It is accompanied by calcite, which in the back part of the specimen partially covers the crystals of wulfenite, with small aggregates of yellowish arsenatian vanadinite crystals, curiously close to pyromorphite. We will send the analysis to the buyer. A specimen more than aesthetic historical, fine quality and from a classic Mexican locality.
