Questions About Opal Diamond Necklace Sets
  • 1stDibs ExpertDecember 4, 2023
    There is no single best setting for a diamond tennis necklace. You can find tennis chains with both prong and bezel settings, and both types can keep diamonds secure when they are well crafted. The biggest difference is that full bezel settings encircle the gemstones, while prongs hug the stones with three or four metal elements, leaving most of their edges visible. Feel free to choose the type of setting that appeals most to you. On 1stDibs, explore a wide range of diamond tennis necklaces.
