A gemologist is a scientist who specializes in the study of gemstones, identifying, grading and appraising those stones. They are able to quickly recognize the quality of a gemstone based on specific details that are specific to the type of stone, both with the naked eye and through magnification. Gemologists are important parts of the jewelry trade, helping customers to analyze and appraise their antique and heirloom pieces, using special gemology tools to evaluate their size, color and shape. They are also an important resource in the trade of precious stones, both grading and evaluating the grade of stones when they are bought or sold.
