Physical properties

Formation & geological history

Formed in hydrothermal veins, pegmatites, and metamorphic environments where silica-rich fluids crystallize. Yellow coloration typically arises from trace amounts of iron inclusions or natural radiation.

Uses & applications

Popular as a polished gemstone for jewelry, pocket stones, decorative display, and metaphysical collecting.

Geological facts

Natural citrine is relatively rare; much of the yellow quartz on the market is heat-treated amethyst or smoky quartz, though natural iron-stained quartz pebbles are also common.

Field identification & locations

Identified by its waxy to vitreous sheen, smooth tumbled texture, hardness capable of scratching glass, and warm translucent color. Common worldwide in gravel deposits and quartz-bearing veins.
