The spike hoop is a hoop earring where one or both ends terminate in a pointed spike rather than closing into a ring - the open end giving the earring a tension and direction that a plain closed hoop lacks. Rachel Zoe runs a thin row of pave CZ along the edge of the hoop in 14K gold over sterling silver, the sparkle tracing the arc all the way to the spike point and amplifying the visual drama of the open terminus. Latch back closure. This is a hoop earring with an edge - literally and figuratively - for the wearer who wants the hoop format to carry some attitude alongside its sparkle.
