Gemology is the science, art and profession of identifying and evaluating
gemstones. It may be considered a branch of
mineralogy. Some
jewelers are gemologists and as such are qualified to identify and appraise gems. There are professional schools and associations of gemologists and certification programs.
Some gemologists specialize in diamonds or pearls, especially difficult areas. The demand for gemology service has grown as more and more synthetic gems such as cubic zirconia come on the market.
