Physical properties
Typically colorless to transparent with a vitreous luster, conchoidal fracture, and no cleavage; Mohs hardness 7, specific gravity about 2.65. The pieces appear irregular, possibly naturally broken or tumbled quartz.
Formation & geological history
Quartz crystallizes from silica-rich hydrothermal fluids, igneous melts, and metamorphic or sedimentary processes. It is common throughout the geologic record, from Precambrian rocks to modern mineral deposits.
Uses & applications
Used in glassmaking, electronics, abrasives, countertops, and ornamental collections; clear crystals may be used in jewelry or metaphysical products.
Geological facts
Quartz is one of Earth’s most abundant minerals and forms in the trigonal crystal system. These fragments may also be clear rock crystal or cleaned industrial quartz rather than complete crystals.
Field identification & locations
Identify by its glassy appearance, hardness sufficient to scratch ordinary glass, lack of cleavage, and conchoidal fracture; common sources include Brazil, Madagascar, Arkansas, and alpine veins.
