Up util recently, the infinity symbol was something you only saw in a high school math class or in some Jane Seymour-designed jewelry. Then, seemingly out of nowhere, the sideways eight started showing up in arm parties all over Pinterest. We could probably chalk this up to how hot spiritual symbols are right now—the cross, the evil eye—or maybe it’s related to the popularity of ABC‘s Revenge. Whatever the origin, we are loving the infinity on jewelry. Click through for some of our favorite bracelets, necklaces, rings and earrings featuring the symbol that never ends.
