Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent, vitreous luster, trigonal crystal structure (though massive in this pebble form), no cleavage, specific gravity of 2.65. Iron staining gives it rustic red/orange hues.
Formation & geological history
Formed from igneous, metamorphic, or sedimentary processes. This specific specimen has been heavily weathered and rounded, likely tumbled by water in a stream or beach environment.
Uses & applications
Common quartz is used in glassmaking, abrasives, and construction. Smooth pebbles like this are often used in landscaping or decorative displays.
Geological facts
Quartz is the most abundant mineral found at Earth's surface. Iron oxidation within the cracks gives this piece its characteristic coloration.
Field identification & locations
Easily identified by its hardness (will scratch glass), conchoidal fracture (where not heavily smoothed), and lack of cleavage. Common in riverbeds and coastlines.
