Carat Weight
Carat Weight is the standard measurement system used to describe how heavy a gemstone or diamond is. One carat equals 0.2 grams, about the weight of a paperclip. This is one of the "Four Cs" (along with Cut, Clarity, and Color) that professionals use to determine a gem's value. When you see this term in resumes, it shows that the person has experience measuring, grading, and working with precious stones. They might have worked in jewelry stores, gem laboratories, or appraisal offices where accurate measurement of gem weight is crucial for pricing and certification.
