Thailand’s gem mining heritage dates back centuries, with Chanthaburi and Kanchanaburi once renowned for world-class rubies and sapphires. While local mines have largely diminished, Thailand has transformed into a global powerhouse for cutting, enhancement, and trading. The country now imports rough from across the world and remains a central hub for the international gemstone market.

Thailand has earned its reputation as a global gem hub through generations of skilled craftsmanship and a highly developed trading ecosystem. Bangkok attracts dealers from every major mining region, offering unmatched access to sourcing, cutting, treatment, and certification—all within a single city.

Bangkok is home to the world-famous Jewelry Trade Center (JTC) and thousands of skilled cutters, traders, and treatment experts. Thailand’s expertise in heat treatment, its efficient global logistics network, and its concentration of international dealers make it a central marketplace for gemstones from across Asia and Africa.
