GemologyGemology (gemmology outside the United States) 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 various gemstones, such as diamonds or pearls. Such specialists are found in fields in which a great knowledge is required, especially in the determination of exceptionally "pure" gems. Recently, the demand for gemological services has grown, as increasing quantities of synthetic gems such as cubic zirconia and fracture-filled diamonds have flooded the gem market. External links
