Our Mission
GemWiki is the definitive online encyclopedia of gemstones, combining rigorous scientific data with cultural and spiritual knowledge. We catalog over 220 gemstones across multiple categories, providing detailed information on physical properties, origins, spiritual meanings, birthstone associations, and care guidelines.
Scientific Rigor
Our gemological data is sourced from the Gemological Institute of America (GIA), Mindat.org, and peer-reviewed mineralogical databases. Each entry includes Mohs hardness, chemical formula, crystal system, refractive index, and specific gravity where available.
