Physical properties
Pale translucent, glassy-looking fragment with irregular fracture; if quartz, Mohs hardness is 7, luster vitreous, and crystal structure trigonal. The image alone cannot confirm composition; it could also be glass or another pale mineral.
Formation & geological history
Quartz forms in igneous and metamorphic rocks and hydrothermal veins over a wide range of geological ages; this fragment’s source is unknown.
Uses & applications
Quartz is used in glassmaking, electronics, abrasives, and jewelry; this small rough piece has little commercial value unless identified as a desirable specimen.
Geological facts
Quartz has no cleavage and typically breaks with curved, conchoidal surfaces; glass can look similar but is usually softer and may show bubbles or sharp-edged fractures.
Field identification & locations
Check whether it scratches ordinary glass and inspect for natural crystal faces or inclusions; common quartz occurs worldwide. A photo is insufficient for reliable identification.
