The threader earring threads through the piercing and hangs on both sides - a format that creates an unusually clean, linear effect at the ear with no visible post or back hardware. Rachel Zoe's version graduates CZ along the thread in rhodium over sterling silver, the stone size increasing as the earring descends for a subtle visual emphasis at the longest point. The threader format is minimal by nature - this is jewelry for the wearer who prefers elegance through restraint and wants her CZ to perform quietly rather than announce itself.
