Physical properties
Hardness of 7 on the Mohs scale, yellow to golden color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms in hydrothermal veins, pegmatites, and sedimentary environments through the crystallization of silica-rich solutions.
Uses & applications
Used in jewelry, decorative items, and optical components due to its piezoelectric properties.
Geological facts
Yellow coloration is often caused by natural irradiation or sub-microscopic inclusions of iron hydroxide.
Field identification & locations
