The mark "DY" on 18k gold typically indicates the manufacturer or designer's initials, often representing the brand or artisan responsible for creating the piece. The "18k" specifies that the gold alloy contains 75% pure gold, which is a standard for high-quality jewelry. Such markings help in identifying the authenticity and origin of the gold item. Always check with a jeweler for verification of marks and quality.
