What does the Carat symbol mean?

The carat symbol (ct) denotes the weight of precious gemstones and pearls, with one carat being equivalent to 200 milligrams. It is a standard unit of measurement used in the jewelry industry to indicate the size and value of a gemstone. The more carats a stone has, the heavier and often more valuable it is, although other factors like cut, color, and clarity also significantly affect a gem's worth.
