Physical properties

Hardness: 7 on Mohs scale; Color: Yellow to golden-brown; Luster: Vitreous; Crystal Structure: Hexagonal (Trigonal); Cleavage: None; Specific Gravity: 2.65

Formation & geological history

Formed in igneous and metamorphic environments, specifically in pegmatites and hydrothermal veins. Natural citrine occurs through the heating of amethyst or smoky quartz within the earth.

Uses & applications

Primarily used as a gemstone in jewelry, as well as in holistic practices and mineral collections.

Geological facts

Natural citrine is quite rare; most 'citrine' on the market is actually heat-treated amethyst. It is known as the 'Success Stone' or 'Merchant's Stone' in folklore.

Field identification & locations

Identify by its transparency and golden hue. Natural specimens often lack the bright white base common in heat-treated amethyst geodes. Found commonly in Brazil, Madagascar, and Russia.
