This necklace from ThinkGeek puts the solar system around your neck. The Complete Solar System Necklace puts the sun front and center, with the eight planets spaced on each side of the necklace. Don’t feel bad for Pluto, though. He may be only a minor planet now, but ThinkGeek arranged for an exclusive version of this necklace with Pluto dangling on the clasp at the back of the necklace, just for their customers. Looking at the alternate views of the necklace made me realize how big this piece of jewelry is (the sun isn’t quite actual size), but it sure will be a conversation starter. With the Complete Solar System Necklace from ThinkGeek, you can not only be the center of the solar system, you can own it too, for only $109.99.
