925 is a standard sign used to mark sterling silver, and the meaning of the stamp is that the silver content in the piece is 92.5% (i.e., the remaining 7.5% is comprised of other elements). Perhaps because the âgoldâ jewelry you are looking at is not actually made of gold.
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.
