This is a situation similar to the iPhone that developed a weird shape on it due to the magnetic sand. We’re not sure which beach this person is on, but she had a similar experience with her bracelet. It collected a large amount of iron from the sand and produced what looked like a large black piece of fuzz on her bracelet.

Like the sand at Tahoe, the iron in the sand at this beach contained large amounts of magnetite and is ferromagnetic. We hope this person wasn’t too mad because we personally think this was a happy accident. The bracelet still looks beautiful. Maybe even more so than before.
