1.1" Metallic Stibnite and Druzy Quartz - China

This is a gorgeous cluster of stibnite crystals with druzy quartz crystal formation, collected from China. The stibnite crystals have great metallic luster, fine striations and are in overall good shape. This specimen comes on a piece of mineral tack within an acrylic perky display case.

Stibnite is a lead-gray mineral made up of antimony sulfide and is the main ore of antimony. It often forms groups of long, shiny metallic crystals radiating out at different angles, which look like something out of a sci-fi movie.

Toxicity Warning: Stibnite (antimony) is toxic and can be harmful if inhaled or swallowed. Most of the risk is long-term, chronic exposure to its dust. While a crystal sitting on your shelf doesn't pose a health risk, you should wash your hands after handling, keep out of reach of children, and please don't lick the stibnites.

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.
