Paris is the seat of the gems and jewellery industry in France and boasts a thriving ecosystem of ateliers, retailers and others involved in the selling, cutting and verifying of gems. One of the most cutting-edge players here is the Paris Gemological Laboratory. Surrounded by the opulence of luxury hotels and renowned fashion houses, the laboratory serves as the epicenter of gemological analysis in France. Established as the only international French gemological laboratory in this prestigious locale, it’s uniquely positioned to cater to clients across Europe. The Paris Gemological Laboratory offers a comprehensive suite of services, including gem identification, treatment detection and origin determination, through meticulously crafted reports and certificates. Expert gemologists specialize in analyzing a wide array of gem varieties from rubies to emeralds and diamonds. Equipped with state-of-the-art analytical tools, the laboratory leaves no stone unturned in its quest for precision and accuracy starting with microscopes, which are the backbone of gemology. Gemologists scrutinize the intricate details of gemstones, enabling them to detect genesis, treatments and origins by studying the inclusions under high magnification. One step further is the digital microscope, which empowers gemologists to explore gemstones with unparalleled clarity and precision. With magnification capabilities up to 5,000x, the Keyence VHX6000 opens a window into the microscopic world hidden within each gemstone. The Paris Gemological Laboratory also employs a refractometer, specific gravity and a polariscope to complete its portfolio of assessment services. By measuring the extent of light refraction, the refractometer provides valuable insights into the mineral composition of gemstones, aiding in their identification and characterization. Utilizing specific gravity measurements, gemologists are able to determine the density of gemstones and offer crucial information about their chemical composition and crystal structure. Finally, the polariscope is used to distinguish between isotropic and anisotropic transparent minerals, noting the unique optical properties that define each gem.
