Colored Gemstone Engagement RingsToday's brides are in search for an engagement ring that reflects their own style. While diamond engagement rings still reign in popularity, current bridal trends are drifting away from the traditional solitaire on a simple band. More and more, 2015 couples are choosing colored gemstone center stones or accent stones for their engagement ring. Colored gemstone engagement rings are fun, unique and can represent birthstones and other important meanings.
