Physical properties

Hardness: 7 (Mohs scale), Color: Pale yellow to golden honey, Luster: Vitreous (glassy), Crystal Structure: Trigonal/Hexagonal, Cleavage: None (conchoidal fracture), Specific Gravity: 2.65

Formation & geological history

Formed in igneous or metamorphic environments through crystallization from silica-rich hydrothermal solutions or magma. Yellow coloration is often caused by trace amounts of iron or natural radiation.

Uses & applications

Used primarily in jewelry (faceted or cabochons), decorative carvings, and as a popular semi-precious gemstone for mineral collectors and practitioners of crystal healing.

Geological facts

Naturally occurring yellow quartz is somewhat rare; much of the yellow quartz on the market is actually heat-treated amethyst or smoky quartz. It is known as the 'Success Stone' in folklore.

Field identification & locations

Identify by its hardness (will scratch glass) and lack of cleavage. Look for characteristic clarity and uneven color distribution. Found globally, with notable deposits in Brazil, Madagascar, and the USA.
