Unlike regular gold plating (GP: Gold Plated), it is a material that is mainly made of an alloy such as brass as the core, and coated with an alloy containing gold at 1/20 (5%) of the total weight. The gold coating layer is 20 to 30 times thicker, and is coated with heat and pressure, so it is also durable and is called "gold-filled". There is almost no worry that the plating will peel off quickly like gold plating. It is a material that allows you to easily enjoy the shine of real gold. Since it is a natural stone, there may be inclusions, small scratches, chips, and dents, but please understand that this is a natural characteristic. The color may look different depending on the device you are using. Please understand.
