Guild Gem Laboratory (Thailand)
Guild Gem Laboratory was founded in Los Ange-les in July 1980 by Mr Charles Carmona. For more than 40 years, GUILD Gem Lab has always been committed to the research, identification, science popularization and promotion of color gemstones, and has rich experience and massive achievements in the field of building a standardized system in the color gem market.
Based on depth academic research background and a large number of research on the origin of color gemstones and market identification data, GUILD Gem Lab has built an enterprise database covering all common gem categories in the market. Focus, accumulation, cohesion and breakthrough. From the start-up appraisal institution on the east coast of the Pacific Ocean to the authoritative appraisal brand based in the Asia Pacific and radiating around the world, every development node of GUILD Gem Lab resonates with the international color gem industry on the same frequency.
Since 1981, Guild Gem Lab has participated in the 40th consecutive Tucson Jewelry Show, providing on-site identification and consulting services. It was also in 1981 that GUILD began to carry out continuous research on the origin of color gemstones and market data collection, and gradually established a solid relationship with the miners, dealers and buyers of internationally famous color gemstones from Colombia, Brazil, Zambia, Thailand, Sri Lanka, Mozambique, Myanmar and other countries, laying a solid foundation for a series of color gemstone identification standards and field gemology research.
