18k yellow gold nose stud. This genuine nose stud features a single natural diamond, approximately 0.02 carats, and is small but authentic. Material: 18k yellow gold Uses one natural diamond (0.02 carats) The entire circumference is secured with a bezel setting, making it less likely to fall out. This product is not plated; it is made by pouring real gold into a mold. Polishing is done in the final process, but polishing marks that can be seen with a 10x loupe will inevitably remain (excessive polishing reduces the weight of the gold and diminishes its asset value, so we aim for the limit). Please understand this as the feel of a 18k gold product. Because everything is done by hand, the post may bend slightly from the impact of stamping the hallmark. Please understand this as a characteristic of soft gold. Leaving body piercings on continuously can not only cause discoloration of gold products but also lead to inflammation due to sebum and dirt from the body. Please remove it during bathing and rinse it lightly with water. Total weight: Approximately 0.13g (actual measurement) Total length: Approximately 9.2mm (actual measurement) Post thickness: Approximately 1.0mm (equivalent to 18G) Diamond size: Approximately 1.9mm (actual measurement) Hallmark: "K18 0.02" stamped on the post Wrapped in cotton wool, placed in a paper pillow case, and shipped via Nekopos.
