Solitaire engagement rings are the most popular setting and are a classic expression of the one true love that will be shared for a lifetime. Featuring one single diamond, set atop a simple band, solitaire diamond rings are timeless, elegant and bold. The statement made by a solitaire setting is all about the purity of the diamond and the band on which it is set. The prongs position the center diamond to catch the most light possible revealing the true beauty and life of the diamond. While a four-prong setting shows a more of the center diamond, a six-prong option is available and offers a slight bit more safety in terms of securing the diamond in the mounting.
