The term "18k RGP" on the inside of a ring stands for "18 karat gold rolled gold plate." This indicates that the ring is made with a base metal that has been coated with a layer of 18 karat gold through a rolling process, giving it a gold appearance while being more affordable than solid gold. The "RGP" signifies that the gold layer is thicker than standard gold plating, providing better durability and wear resistance.
