Platinum engagement rings are especially popular today and are the perfect complement to platinum wedding rings. Platinum rings with diamonds provide a truly stunning effect. Two of the more popular styles of platinum engagement rings include tension-set and prong-set.

Tension-set platinum engagement rings usually feature a solitaire diamond that is mounted between the ends of the platinum ring and held in place under the tension of the metal.

Prong-set platinum engagement rings also feature a solitaire diamond that is mounted in a "claw" consisting of between 4 to 6 prongs. The latter is also referred to a Tiffany setting. Prong-set platinum engagement rings are popular as they can make the diamond appear larger and by lifting it higher off the ring, allow more light to reach the diamond.

Platinum engagment rings are sometimes inlaid with gold or titanium for a beautiful contrast.
