Gemological laboratories are specialized facilities that analyze and evaluate gemstones and precious metals. They use advanced equipment and techniques to determine the quality, authenticity, and characteristics of gems, such as diamonds, sapphires, and emeralds. These labs provide detailed reports that help buyers and sellers understand the value of their stones. In addition to grading gemstones, gemological laboratories also conduct research and education in the field of gemology. They may offer courses and certifications for aspiring gemologists, helping to advance knowledge about gemstone identification, treatments, and market trends.
