Silver Tone 18 KRGP Gold Plated Teardrop Rhinestone Charm Necklace Peach

In great condition regular wear necklace marked as "18KRGP", which means it's 18k rolled gold plate. Here's what you need to know: Rolled gold plate (RGP) is a type of gold plating that's thicker and more durable than standard gold plating. It involves bonding a thin layer of gold to a base metal (usually brass or copper) through a mechanical process. 18k gold refers to the purity of the gold layer, indicating that it is 75% gold and 25% other metals. While RGP is more durable than standard gold plating, it's not as durable as solid 18k gold. Over time, the gold layer can wear off, exposing the base metal underneath.
