What more universal symbol of science is there than a carbon atom? Atoms are the building blocks of everything -- the stuff of stars and humans alike. They hold relevance to biology, climate science, physics, and basically any field studying the natural universe. This carbon atom necklace is both subtle and striking. A dark grey Swarovski pearl on a hand-wrapped silver wire makes the nucleus, and the 1 1/4" pendant comes hung on an 18" sterling silver chain. This piece of science-inspired jewelry matches everything, from t-shirts to prom dresses.
