Please consider after viewing the profile. This is an unused necklace. I do not know the material. The chain and other parts are gold-colored. There may be a difference in color between the photos and the actual product. Since many parts are used, there may be some slight cloudiness or discoloration. Length when the chain is laid flat... approximately 43cm This is just a rough measurement, so please use it as a reference! Although it is unused, it has been stored at home for a while, so please consider this before purchasing. Color... Gold系 (Gold-toned) Material... Other
