Physical properties
Opaque to slightly translucent white, rounded and unbanded; quartz has Mohs hardness 7, vitreous luster, and no cleavage. The image is blurry, so the specimen’s properties cannot be confirmed visually.
Formation & geological history
If quartz, it formed as silica crystallized in rock or filled fractures, then was rounded by transport and abrasion. Its geological age and source cannot be determined from the image.
Uses & applications
Common quartz is used in glassmaking, electronics, and decorative objects; a pebble of this size is generally ornamental or a teaching specimen.
Geological facts
Quartz is one of Earth’s most abundant minerals and occurs in many rocks and sediments.
Field identification & locations
The pale, rounded shape is consistent with a quartz pebble, but other light-colored stones could look similar. A scratch test and closer inspection of luster and fracture would help identify it.
