Thank you for looking. This is a set of 35 earrings and piercings. ◆ I have no knowledge of gemstones, so I do not know the materials. ◆ Please understand that these are items stored by an amateur. ◆ They are basically unused, but please understand that some are old. ◆ Please understand that there may be dirt from age, bent clasps, or missing parts. ◆ The accessories will be shipped together in small bags. Thank you for your understanding.
