Microscopy The microscope remains the most important tool in gem identification. A thorough and detailed analysis reveals a lot of information about a gem - it has a story to tell - about its origin - the depth within the earth's crust, the temperature and pressure conditions, the chemical environment in which it has formed, and much more. Observation of internal features is still the most valuable technique in identifying the nature of a gem. In some cases, the features are so characteristic, that they not only tell the identity of a gem, but also its origin. Microscopy remains the core of any gemmological study and complements 'the many' spectroscopic analytical tools, in determining the nature, whether natural or synthetic and the type and degree of treatments performed. At Shree Radhe Krishna International Gems Testing Laboratory, every analysis is started with a detailed microscopic observation.
