A solitaire engagement ring is a classic and timeless design that features a single centre stone set prominently on a simple band. The term solitaire refers to the single diamond. The stone is commonly cut in a round brilliant shape, but it can also be cut in other shapes such as princess, oval, emerald, or cushion. The focus of a solitaire ring is on the beauty and brilliance of the centre stone, which is often held in place by prongs or a bezel setting. The band of a solitaire engagement ring is typically plain, allowing the centre stone to be the main attraction.
