.999 Silver bezel cup with a decorative, serrated edge and holds one 6mm round cabochon, flat-back stone, or crystal. This bezel is a great choice for jewelry designs made with .999 Aussie Metal Clay Silver, .960 Aussie Argentium Metal Clay or .960 Sterling Metal Clay. You can embed in your Aussie Metal Clay or attach to your piece with Kim’s Claystay and fire in place. Set your stone after firing, unless a fireable stone. Use with stone or glass cabochons, for flat-back stones or crystals, or with resins to create everything from earrings to cuff links to pendants. You can also solder the bezel cup to a finding or design, and set as desired.
