Physical properties
Hardness of 7 on the Mohs scale, pale yellow to greenish-yellow color, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed hydrothermally in igneous and metamorphic environments, often treated with irradiation and heat to achieve its distinct yellow color.
Uses & applications
Widely used in jewelry making for rings, pendants, and earrings, as well as valued by collectors.
Geological facts
Natural yellow quartz is often called citrine, but irradiated varieties treated to reach a bright lemon hue are specifically marketed as lemon quartz.
Field identification & locations
Identified by its distinct lemon-yellow hue, glass-like luster, and high scratch resistance; commonly sourced from Brazil and Madagascar.
