This is the viereck onyx ring from h'eres. It's a brand designed by Taisei Kanayama, and the square onyx is very cute. This item is already discontinued and I think it's rare. Please take this opportunity. Color: Silver x Black Material: Silver 925 Size: Approximately size 18 (Japanese size) There is some wear and tear, but it's still usable. martine rose y project sacai unused kudos namacheko jieda dulcamara SUNSEA needles essay YAECA auralee kolor littlebig toga black eye patch doublet a-cold-wall shoop raf simons sulvam lownn ourlegacy Gosha rubchinskiy COMME des GARCONS homme plus comoli whowhat uru ryo takashima Masaki Suda gap polo ralph lauren lacoste FRED PERRY supreme palace stussy graphpaper Y-3 yohji yamamoto daiwa pier39 stein yoke trunk project dairiku ttt_msw Y2K cornerstone 8on8 t/sehne our's
