Round Cut Engagement Rings

It's easy to see why round engagement rings are the most popular of all our diamond shapes. The brilliance and fire of a round diamond means if you're looking for sparkle, then this is the perfect engagement ring for you. Carefully cut to optimise light reflection, round brilliant cut diamonds as they are also known, provide you with an exquisite shine that is second to none. Round cut engagement rings are seen to be the traditional option for popping the question because the classic shape has a versatility that is suited to all engagement ring styles and is available in all three gold options as well as platinum.
