Query: I don't recommend this ring.

Although this ring is gorgeous, and very ornate (for such a small ring). There was one drawback. It turned my finger green. I only wear sterling silver or white gold jewelry, and I have many sterling silver rings, none of those rings have turned my finger green. This lead me to believe that the ring was not sterling silver as it states on the website. I would not recommend buying this ring, or any jewelry from the silver insanity company.
