The "14k" on a ring indicates that the metal is made of 14 karat gold, which means it contains 58.3% pure gold mixed with other metals for added strength and durability. The "fb" may refer to "filled base" or "fine bezel," but it's less common and not a standardized term. Always check with a jeweler if you're uncertain about specific markings on jewelry.
