Show off your love for the solar system with this out-of-this-world necklace from ThinkGeek. The adjustable 21-inch-long chain—which is brass plated with imitation rhodium—holds the celestial bodies astronomy fanatics know and love: Earth, our moon, the planets, the sun, asteroids, and even Pluto. All of the astrological objects are represented with semi-precious stones. For instance, The Sun is dyed jade, Mercury is white turquoise, and the asteroid belt is snow stone.
Those who are sticklers for correct ratios will note the size of the necklace's Jupiter, while the asteroids were enlarged in order to make them more visible. Looking for more space-themed jewelry? Pair the necklace with these constellation earrings.
