Unlike regular gold plating (GP: gold plated), it is a material that is mainly made of an alloy such as brass as a core, and coated with an alloy containing gold at 1/20 (5%) of the total weight. The gold coating layer is 20-30 times thicker, and it 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.
