Physical properties

Hardness: 7 on Mohs scale; Color: Pale yellow to translucent gold; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: Approx 2.65

Formation & geological history

Formed in hydrothermal veins or igneous rocks like granite, subsequently weathered out and rounded by water transport in riverbeds or marine environments

Uses & applications

Used for decorative landscaping, jewelry (small tumbled stones), spiritual/metaphysical collecting, and industrial glass/silicon manufacturing

Geological facts

Yellow varieties of quartz are often called Citrine if naturally colored by iron, though many commercial pebbles are heat-treated amethyst or simply iron-stained common quartz

Field identification & locations

Identified by its high hardness (scratches glass), waxy to glassy luster, and smooth water-worn surface; commonly found in gravel pits and river beds worldwide
