Silver-plated brass calibrated bezel cup mounting accepts a 25x18mm oval cabochon or flat-backed crystal. A solid-backed bezel cup offers multiple benefits to the jewelry designer: it intensifies the color of semi-transparent stones, adds background for glass and resin materials and offers a sturdy backing for clay-based creations. Bezel cup depth is approximately 2mm. Glue-on finding comes with a built-in bail.
