The Greek symbol “Beta” means a lot of different things to a lot of different people. For rock climbers, it’s the route to get to the top of a particularly tricky bouldering puzzle. For biologists, beta sheets play an important role in protein folding. And in physics, beta radiation is a stream of unbound energetic electrons. Do you know someone with lots of important betas in their life? If so, our necklace will make the perfect gift. Give it to a rock climber, a biochemist, a physicist, or Greek philosopher.
