Round is by far the most popular diamond shape selected by brides for their engagement ring. There are many reasons for this, including the fact that a round diamond is very versatile in terms of balancing the clarity, cut, and color of any quality diamond. Here at Professional Jeweler, we carry a variety of round diamond engagement rings for you to choose from. Looking for something simple and delicate? We recommend a single round diamond solitaire. For something a little more complex, rounds pair well with pave settings and square or round accent diamonds. No matter what you have in mind or what your budget, we have plenty of round diamond rings to choose from.
