This is an AMACA baroque pearl necklace. I forgot to confirm at the time of purchase, but I believe it's freshwater pearls. It's been used, and I mainly wore it over knitwear. As it's a natural product, there may be some unevenness in the luster from the beginning, but I don't think there are any noticeable scratches or stains from use. The AMACA logo clasp has some slight dullness. It's carefully made with an all-knot finish, with knots between all the pearls. It's approximately 40cm in the state shown in the photos, and can be extended by about 6cm using the adjuster. The largest pearl in the center, which is horizontal, is about 14mm wide. I have a cat, so even though I'm careful, cat hair may get mixed in.
