This delicate bracelet is elegant yet has a strong presence. What is 14kgf (14-karat gold filled)? Unlike regular gold plating (GP: gold plated), 14kgf uses an alloy such as brass as its core metal, and coats it with a gold alloy that makes up 1/20 (5%) of the total weight. The gold coating layer is 20-30 times thicker, and is applied using heat and pressure, making it highly durable. It is also known as "gold filled." Unlike gold plating, there is almost no worry of the plating peeling off quickly. It is a material that allows you to easily enjoy the shine of real gold. As 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 appear different depending on the device you are using. Please understand.
