Round Diamond Necklaces

Many people run into problems when buying or wearing round diamond necklaces, things like uncertified diamonds, loose settings, or pieces that don’t sit right on the neckline. These issues can cause more than just frustration; they often mean wasted money, lost stones, or a necklace that quickly loses its shine.
