14k TC typically refers to "14-karat tri-color gold," which is a type of gold jewelry made from a blend of three different colors of gold—usually yellow, white, and rose. The "14k" indicates that the gold is 58.3% pure, with the remaining 41.7% consisting of other metals for added durability and color.
