Penrose Clicker from Tether Jewelry

Lionel Penrose, along with his son Roger, created two of the more famous “impossible objects” optical illusions: the Penrose Tribar and the Penrose Stairs. These clickers have a system of crosshatch linework that appears to bend and morph as it weaves into faceted points and repeating patterns. Each ring has a hinged clasp for easy insertion and removal.

Cast in stainless steel, these are sturdy and nonreactive when worn. Available in “nude” steel, with no plating; black PVD-coated stainless steel; and yellow- and rose-gold-plated over yellow-PVD-coated stainless steel.
