Marc Jacobs crystal solitaire ring

Marc by Marc Jacobs faux solitaire diamond ring oversized. This is from the shop Marc Jacobs had in Manhattan (2007) in which they sold inexpensive random stuff. The ring is not branded but it was purchased there. One owner only. Adjustable ring band in silver tone metal. Opened to a size 7.5ish but adjustable. Signs of wear on the band with slight tarnish/discoloration. I have the same ring but bigger as well, check other listings.
