【615】Natural Stone Pink Chalcedony 14kgf Necklace Chain Materials: All 14kgf Necklace with adjuster Size: Approximately 40cm + 5cm in length 《What is 14kgf?》 Unlike gold plating, which has a thin gold layer that easily peels off, 14kgf has a gold layer that is 100 times thicker, resulting in a very beautiful finish. In Europe and America, it is classified as jewelry rather than an accessory, so you can use it with confidence for a long time. Also, 14kgf is nickel-free, so it is considered a material that is less likely to cause metal allergies. (Individual reactions may vary, so it does not guarantee that everyone will not have an allergic reaction. Please refrain from using if it does not suit your skin.)
