Skull Jewelry by WildThing Studio
WildThing is an Israeli design studio with some truly lovely and simple skull jewelry. I say simple for the aesthetic and not for the process, as anything made well by hand can only be done with skill and patience. Their ideas and execution seem to be in good harmony.
WildThing have an online store on Etsy so be sure to check out some reasonably priced, hand crafted, skull jewelry.
