Color Master
A Color Master is a specialized professional in the gemology and jewelry industry who is highly skilled at evaluating and grading the color of gemstones and diamonds. They play a crucial role in determining a gem's value and quality. Think of them as the "color experts" of the jewelry world - similar to how wine sommeliers are experts at identifying subtle differences in wines. They use special lighting and their trained eye to assess and grade stones according to industry standards. This role might also be called a "Color Grader" or "Color Stone Specialist" in some companies.
