Yehwang's specialty is jewelry made of stainless steel and gold plated metal jewelry. Stainless steel is discoloration-proof and is not affected by oxidation. This makes it an ideal material for long-lasting jewelry. To make gold plated jewelry a thin layer of gold, white gold of rose gold is applied to metal jewelry. The stainless steel and gold plated jewelry from Yehwang are of high quality but we recommend to not wear the jewelry when sleeping, showering and exercising.
