Pyromorphite is a mineral species composed of lead chlorophosphate: Pb5(PO4)3Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. Crystals are common, and have the form of a hexagonal prism terminated by thebasal planes, sometimes combined with narrow faces of a hexagonal pyramid. Crystals with a barrel-like curvature are not uncommon. Globular and reniform masses are also found. It is part of a series with two other minerals: mimetite(Pb5(AsO4)3Cl) and vanadinite (Pb5(VO4)3Cl), the resemblance in external characters is so close that, as a rule, it is only possible to distinguish between them by chemical tests.
They were formerly confused under the names green lead ore and brown lead ore (German: Grünbleierz and Braunbleierz) it was named pyromorphite by J. F. L. Hausmann in 1813. The name is derived from the Greek for pyr (fire) and morfe (form) due to its crystallization behavior after being melted.
COLLECTORS’ INFORMATION: Pyromorphite is collected for its unusual chemistry, pleasing lime-green color, and hexagonal crystal shapes that often have distinctive, cavernous or pitted terminations.
The colors in the image are different from the actual piece since in reality it’s not that smoky. The worst part is, the back with the pyrite seems to have less pyrite there than what was presented in the image. It’s crumbled but there were no pieces in i
so sorry to hear , could you return for a refund?
The luster doesn’t look exactly the same and the color appears a tad darker but it’s the same stone and accurate based on the selling page. Still a really good buy and well packaged
