In the context of diamond jewelry, CTW stands for âcarat total weightâ (or âcarats total weightâ). The term refers to the sum of the weights of all diamonds mounted in a piece of jewelry. This ring is 1/4 CTW, meaning that the black diamonds in it have a total weight of 0.25 carats. As an example, suppose you have a ring with one center diamond that weighs 1 carat and two smaller diamonds of 0.5 carats each.
