About
Gemstone Map is an open, ad-free interactive atlas connecting consumers, collectors and crystal lovers with the true geographic origins of gems.
Data sources
Mine coordinates and deposit classifications are drawn from the USGS Mineral Resources Data System (public domain), enriched with curated mineralogical records for the world's legendary gem localities — Mogok, Muzo, Kashmir, Merelani and beyond. Origin characteristic notes follow standard gemological literature.
Ethical sourcing labels
OK responsible / low-risk supply chain · Caution artisanal or governance risks documented · Conflict conflict-zone or documented abuses. Labels are indicative, not certifications. Always buy from vendors providing transparent provenance.
