Gemstones are not merely beautiful, faceted rocks; they are windows into the Earth’s history. Locked within their crystalline structures are tiny "fingerprints"—inclusions—that tell the story of their formation, origin, and authenticity. For gemologists, dealers, and collectors, understanding these inclusions is paramount. The ultimate reference for this microscopic world is the renowned .
