Clip-on Dangle Crystal Earrings

For sale is a pair of unique clip-on earrings. The top rhinestone has an unusual geometric shape and from it attaches a rectangular silver "bar" which has a large faceted crsytal pendulum. There is a "patent pending" stamp on the back. At first glance, I was going to pass these beauties by, then I realized I had not seen another pair like them. Please excuse the holder (pen). I am much better at finding treasures than displaying them !
