In jewelry, "TU" typically stands for "Trade Union," indicating that the item is produced by a manufacturer or artisan who is part of a trade union. This marking can signify that the piece adheres to certain standards of craftsmanship and ethical labor practices. It's important for consumers who value fair labor conditions to look for such markings. However, markings can vary in meaning depending on the context and region, so it's always good to verify with a jeweler.
