2.8" Pink-Orange Stilbite Crystal Cluster on Quartz Chalcedony - India

This is a beautiful, 2.8" long, pristine pink-orange stilbite crystal cluster that formed in association with quartz chalcedony, collected from India. The crystals are in excellent condition and the specimen has a natural aesthetic presentation.

Stilbite is probably the most common zeolite found in these deposits. Crystals often form flowery, bowtie or hourglass shaped structures and come in a variety of colors. Some of the most beautiful colorations are the pink or peach tints.

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.
