Physical properties
Hardness: 7 on Mohs scale; Color: Creamy white to translucent yellowish; Luster: Vitreous to waxy; Crystal Structure: Trigonal; Cleavage: None; Specific Gravity: 2.65.
Formation & geological history
Formed from molten silica cooling in igneous rocks or as veins in metamorphic environments. This specific specimen has been rounded and smoothed by water erosion through transport in a river or coastal environment.
Uses & applications
Used in glass manufacturing, electronics (piezoelectric properties), abrasives, and as a low-cost decorative garden stone.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust. These small pebbles are often referred to as 'river stones' or 'sea glass' neighbors when found in nature.
Field identification & locations
Identify by its hardness (will scratch glass) and lack of cleavage. Found worldwide in riverbeds, beaches, and gravel pits.
