Was a merchandiser for Chloe + Isabel and these were all display pieces (never worn) except for a few earrings (I will state specifically when I’ve worn something). Any discoloration is natural (ex: sterling silver needs to be cleaned on the regular) as these were all stored correctly. I no longer have the catalogs to write the exact names. Feel free to ask more questions but since there are so many c+i pieces, this was easier to post than specific product blurbs.
