This is an easy-to-wear single pearl necklace. Unlike the usual single pearl design, this necklace features K18 gold mirror ball-shaped parts above and below the pearl. The mirror ball parts sparkle and reflect light, creating a glamorous atmosphere. The charm is removable, so it can also be used as skin jewelry with just the chain. It can also be paired with other charms. The chain appears to be a screw chain. It's delicate, but it also sparkles when it catches the light. Material: K18 YG, Pearl Weight: Approximately 1.9g (including pearl charm), Approximately 1.1g (excluding pearl charm) *Measured with a household scale. Please allow for slight variations. Length: Approximately 40cm (measured with the clasp attached. Please refer to the 10th photo) I have used this occasionally after purchasing it. I take it off immediately when I get home, so there is no major damage. The pearl also appears to have no noticeable scratches, but there may be some natural imperfections like dimples. This is a pre-owned item, and some wear and tear may occur due to use, such as around the clasp. If you are concerned about even minor scratches, please refrain from purchasing. I have included photos taken from different angles, so please take a look. Please purchase only if you understand that this is a pre-owned item. Please refrain from purchasing if you are overly critical. Returns and exchanges are not accepted to prevent issues such as product substitution. 18K 18 karat gold K18
