Navajo sterling silver inlay earrings by Ray Tracey Knifewing. These fantastic, articulated earrings consist of a rectangle of black onyx inlay on the top, with an lightening bolt arrow of silver at the bottom. The black onyx in these earrings is very reflective, and any imperfections you see are only reflections. They measure 43mm long and 15mm wide. The back of each earring is marked sterling, along with the Ray Tracey Knifewing maker's mark. I have replaced the earring clutches with nice new large sterling clutches. They are in excellent condition, showing only very light wear. These earrings date to the 1970's.
