What does 14.k R.G.P on a ring mean?

The inscription "14.k R.G.P" on a ring indicates that the ring is made of 14 karat gold, meaning it contains 58.3% gold mixed with other metals for durability. The "R.G.P" stands for "Rolled Gold Plate," which means that the ring has a layer of gold mechanically bonded to a base metal, providing a gold appearance at a lower cost. This type of marking is common in costume jewelry or affordable gold jewelry.
