This ring is made with Stealth Sterling Silver fill wire. The centerpiece gemstone is an Sphene Facet.
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 through simple chemistry. I am basically using a jewelry patina which speeds up the oxidation process of the silver and turns it black. The black color is not permanent, eventually the pendant will adapt to the wearer and the black will transform into shiny silver on the high spots.
