The "RR" hallmark on gold jewelry typically indicates the manufacturer or designer's mark, signifying that the piece was made by a specific brand or artisan. In some instances, it can also represent the quality or purity of the gold, although this is less common. Hallmarks are used to ensure authenticity and to provide information about the metal's composition. Always check for additional hallmarks to confirm the gold's karat and origin.
