Physical properties
Hardness of 7 on the Mohs scale, white to milky color, vitreous to waxy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed in igneous, metamorphic, and sedimentary environments through the crystallization of silicon dioxide-rich hydrothermal solutions or cooling magma. Can be found globally.
Uses & applications
Used widely in decorative polished stones, tumbling, lapidary arts, jewelry making, and metaphysical practices.
Geological facts
Quartz is one of the most abundant and versatile minerals on Earth, forming the basis for many gemstones and industrial applications including electronics and glassmaking.
Field identification & locations
Easily identified by its high hardness (scratches glass), smooth tumbled shape, and lack of cleavage. Common in riverbeds and rock shops worldwide.
