What is 18K gold plated jewelry?
18K gold plated jewelry is a type of jewelry where a thin layer of 18-karat gold (75% pure gold mixed with 25% other metals) is electroplated onto a base metal (such as brass, copper, stainless steel, or zinc alloy) to create the luxurious appearance of solid gold at a fraction of the cost.
