This piece is made with Stealth Sterling Silver and 14k Rose Gold Fill wire. The centerpiece is a Green Tourmaline Crystal.
All of Third Eye Assembly's rings can be stretched up a half size, but that is the only adjustment that can be made.
The Black Wire or Stealth Sterling, as I like to call it, is made with Sterling Sliver process though patination. I use simple chemistry which speeds up the oxidation process of the silver and turns it black. The black color is not permanent, eventually the object will adapt to the wearer and the black will transform into shiny silver on the high spots.
