An infinity design solitaire engagement ring is always an excellent way of symbolizing eternal love in a relationship. This simple solitaire mounts a stunning center diamond upon a plain metal band that is twisted into an infinity shape that revolves around the entire ring. The effortless design is one that is optimal to show off a perfect diamond that needs nothing else to show off its natural beauty. The band is 4 mm in width and can be made from platinum, or 14kt or 18kt gold and rose, white, or yellow colored metal options.
