Why not, there are a number of designs available for such beautiful diamond rings, and some of those appealing designs are given below. Rose Cut Diamond Ring In this design, a huge rose-cut diamond of 5 carats is flaunted at the center of a platinum ring by means of a bezel setting. Additionally, the overall appeal of the ring is bumped up by giving a rope-like finish to the metal settings as well as the diamond ring band. Filigree Diamond Ring Filigree patterns are really popular in antique diamond rings. Here, a medium-sized round brilliant cut diamond is secured at the center of a platinum ring using a traditional claw setting. Additionally, the diamond ring band is embellished with intricate filigree detailing. Halo Diamond Ring There will be no settings other than a halo setting in order to wow up your antique diamond solitaire engagement rings. In this design, an oval-shaped diamond is held at the center of an 18k yellow gold band by means of prongs as well as a halo of accent stones. In addition, the diamond ring band is enhanced by displaying beautifully milgrain works.
