3.2" Galena, Quartz and Pyrite Association - Peru
This beautiful specimen contains an association of pyrite, galena and quartz crystals. It comes from the Huanzala Mine in Peru and the entire piece measures 3.2" wide.
Galena is a lead-based mineral and the primary ore of lead, and has been used for its lead content for thousands of years. Galena typically displays a gray metallic luster and forms cubes or octahedral crystals. The chemical composition of galena is PbS.
While galena will not pose a health hazard by sitting on the shelf or even from casual handling, we suggest washing hands following handling due to the mineral's lead content.

About Pyrite
Pyrite, or iron pyrite, is best known as “Fool’s Gold” thanks to its bright metallic luster and pale brass-yellow color, which can easily be mistaken for real gold in poor lighting. With the chemical formula FeS₂, pyrite is the most abundant sulfide mineral on Earth and forms in an impressive range of geological environments.
One of pyrite’s defining features is its remarkable diversity of crystal habits—over 20 documented forms—making it one of the most morphologically varied minerals known. It commonly occurs as sharp cubes, octahedra, and pyritohedra, but also forms pentagonal dodecahedra, penetration twins, striated combinations, and complex modified forms prized by collectors. It can develop as massive veins, nodules, botryoidal growths, and fine druzy coatings that shimmer brilliantly under light. Whether glittering in tiny clusters or displayed as perfectly geometric crystals, pyrite showcases an extraordinary range of natural architecture and visual appeal.

About Quartz
Quartz is the name given to silicon dioxide (SiO2) and is the second most abundant mineral in the Earth's crust. Quartz crystals generally grow in silica-rich environments--usually igneous rocks or hydrothermal environments like geothermal waters--at temperatures between 100°C and 450°C, and usually under very high pressure. In either case, crystals will precipitate as temperatures cool, just as ice gradually forms when water freezes. Quartz veins are formed when open fissures are filled with hot water during the closing stages of mountain formation: these veins can be hundreds of millions of years old.
