Pearl Necklace Size: 7.5-8.0mm Clasp: Silver Weight: 37g Length: 41cm Please note that the size is measured by hand, so there may be slight variations. The above description was written, and I purchased this on Mercari a few months ago, but I don't seem to be using it, so I'm putting it up for sale. There is no certificate of authenticity. There are dimples, scratches, and cracks. The shape is also irregular, but I think it's fine for everyday use. If you need it, I will include the jewelry case in the image. (It's from a jewelry store, and I've kept it at home since I bought the necklace.) If you don't need it, I will ship it in simple packaging, so please let me know in the comments. Color: White
