The SSEF laboratory was initially established to serve the Swiss gemstone and jewellery trade, but it has since expanded to serve private clients.
  3. GIA - The Gemological Institute of America, or GIA, is undoubtedly the most well-known gem research laboratory. Established in 1931 by Robert M. Shipley with the goal of "protecting both buyers and sellers of gemstones by establishing and preserving the criteria used to determine gemstone quality." Robert M. Shipley worked as a jeweller in the 1920s. The study, gem identification, diamond grading facilities, and educational programmes are the four key areas in which the GIA works. The GIA's most famous singular contribution to the field of gemstone classification is the establishment of the Four C's concept within its International Diamond Grading System in 1953, which is still used to classify diamonds more than half a century later.
  4. GRS lab - GRS research is primarily concerned with the identification and characterisation of high-quality coloured gemstones since its establishment in 1996 by Dr Adolf Peretti; the company has specialised in identifying gemstones from newly discovered mines and the determination of origin for gems mined from conventional mining regions. Colour grading and gemstone colour markings, such as the well-known GRS-type Pigeon's Blood rubies and GRS-type Royal Blue sapphires, are among their specialities. They have labs in Hong Kong, New York, Bangkok, and Switzerland, among other places.
