Yellow Quartz (Citrine Quartz Pebble)

Physical Properties

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

Formation & Geological History

Formed in igneous or metamorphic rocks through the crystallization of silica-rich fluids. Natural yellow coloration is often caused by trace amounts of iron or aluminum. This specimen appears as a water-worn or tumbled pebble, likely shaped by river or beach erosion.

Uses & Applications

Used primarily in jewelry (as a gemstone), crystal healing practices, decorative home decor, and as entry-level mineral specimens for collectors.

Geological Facts

Citrine is known as the 'Success Stone' or 'Merchant's Stone' in folklore. While natural citrine is rare, much of the common yellow quartz on the market is actually heat-treated amethyst or smoky quartz.

Field Identification & Locations

Identify in the field by its hardness (will scratch glass), lack of cleavage, and translucent yellow hue. Commonly found in Brazil, Madagascar, and Russia. Look for smooth, water-worn shapes in gravel beds or river deposits.
