Physical properties

Hardness of 7 on the Mohs scale, orange to yellowish-brown color due to iron inclusions, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65

Formation & geological history

Formed in hydrothermal veins and pegmatites, often weathered and smoothed by water transport in sedimentary environments over millions of years

Uses & applications

Used in crystal healing, decorative items, lapidary arts, and gemstone jewelry

Geological facts

Quartz is one of the most abundant minerals on Earth, and the orange color is typically caused by microscopic inclusions of hematite or limonite trapped during crystallization

Field identification & locations

Easily identified by its hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture; commonly found in riverbeds, gravel bars, and pegmatite deposits worldwide
