One of the necessary pieces of equipment in the modern gem lab. Used for gem ID, detection of certain treatments in pearls, coral and jade. Can also be used to discern synthetic or heated Spinel from its natural unheated state.


Today a tool that is considered mandatory for a professional and modern gem lab. It can be used for classification of diamond types, detect treatments in many gems as well as differentiate between synthetic and natural alexandrite, beryl and quartz. Used in conjunction with ocular examination for judging amount of fillers in emeralds and other gemstones.
