By using gold, it is less likely to discolor than conventional gold. The brilliance is further enhanced and lasts longer by coating with a metal with a higher gold content (compared to normal). However, as it is a plated product, changes due to sulfidation, weathering, and deterioration may occur, so please understand. Although it is less likely to cause allergies than regular plated materials, individual differences exist. What is surgical stainless steel? It uses 316L, the same material as medical instruments used in surgery, and is less likely to cause metal allergies. In the case of gold, nickel-free plating is applied, so there is a possibility of an allergic reaction compared to the silver color.
