Wraps are wedding rings that have stones or designs that come up and over the engagement ring (usually on either side of the center stone). This offers some amount of protection to the center stone, while aligning the additional stones/designs with it. The result is that the overall appearance looks more like one ring than 2 separate elements. Wraps work best with solitaire styles, but can often be customized by a professional jeweler to fit with certain other styles!
Ring Guards are similar to wraps, but fit on either side of the engagement ring forming a type of "sandwich" effect. This is perfect for those of us who desire symmetry! The engagement ring slides down between the two sides, and the result is, again, purposeful and gives the appearance of one design!
