Banana Bob Earrings

Banana Bob National Geographic Earrings. I don't have much info on these, and I don't know the exact material. These are clip on dangle earrings, with 5 charms per side, stones are emerald and rhinestone (from what I can find). Both earrings have a dolphin, turtle, penguin, and panda, with one having a dinosaur, and the other whale. Definitely a unique and interesting piece of jewelry. Measures 3 1/2" tall x 1 3/8" wide.
