The inscription “1KS” on a diamond ring typically refers to the diamond’s carat weight and clarity. The “1” represents the carat weight, indicating a 1-carat diamond, while “KS” could be shorthand for “karat solitaire” or a specific manufacturer’s mark. If it means “karat solitaire,” it suggests the ring features a single 1-carat diamond as the centerpiece. However, it’s also possible that “KS” is the jeweler’s or designer’s hallmark, which is a unique stamp used to identify their work. To confirm its exact meaning, you’d need to check with the jeweler or refer to accompanying paperwork like the diamond’s certificate.
