Physical properties
Hardness of 7 on the Mohs scale, yellow to orange-brown color, vitreous luster, hexagonal crystal system, no cleavage, specific gravity of 2.65
Formation & geological history
Formed within volcanic or sedimentary rocks where silica-rich groundwater fills cavities or gas bubbles over millions of years, crystallizing into quartz. Many commercial yellow citrines are naturally occurring quartz heated or heat-treated amethyst.
Uses & applications
Used primarily in jewelry, decorative ornaments, and crystal healing collections
Geological facts
Natural citrine is relatively rare; the vast majority of bright yellow and orange citrine sold on the market is actually heat-treated amethyst or smoky quartz.
Field identification & locations
Easily identified by its characteristic yellow to amber crystal points inside a hollow rock matrix (geode). Commonly sourced from Brazil, Madagascar, and the USA.
