A little obsessed at how perfect this ring is! Minimalist elegant charm!!! Metal is Copper, Stone is Cubic Zirconia. Open in front so totally resizable!! Love it because I've worn it so many ways!!! You can super extend it ( see last pic ) to create a unique style to you! I've also worn it as a toe ring.... Obsessed!! Just keep in mind if you adjust the size alot of different times that it's still a small piece of metal so you have to treat it gently and with care :)
