The marking "14kt" on a necklace indicates that the piece is made of 14 karat gold, which contains 58.3% pure gold mixed with other metals for durability. The "s4" designation is not a standard marking and could refer to a specific design, collection, or manufacturer's code. It's advisable to consult with a jeweler for an accurate interpretation of the "s4" designation.
