Pyromorphite in the Member Box — this one is from Guangxi. The color is the first thing anyone notices: that electric lime-green comes from the lead in the crystal structure (Pb₅(PO₄)₃Cl). It's one of the few lead minerals that actually looks friendly, and the hexagonal prism habit is textbook. Slightly soft (3.5–4) and heavy — you'll feel the density the moment you pick it up. Worth noting: Guangxi green pyromorphite has been one of the cleanest new-locality finds of the last decade.
