This piece is made with Stealth Silver and features a Opal as the centerpiece. The flare on this Opal is blue with green sparkles.
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 ring will adapt to the wearer and the black will transform into shiny silver on the high spots.
