O.C.D. Circle Grayscale Charm Pendant SOS

My OCD (Oxidized Collection of Designs) grayscale pieces play with three key words: movement, color and shape. Movement = of the pieces of the piece. Color = of the sterling silver at its darkest (oxidized) and lightest. Shape = of the actual centerpiece. These are fun chic pieces. Materials include::: Sterling Silver Size of largest circle:depth = 0.13 incheswidth = 0.78 inchesheight = 0.91 inches (total height includes jump ring) Chain is 20 inches long cable chain with a lobster clasp. This piece is super fun and zen like to play with, flicking the circles to orbit.
