Ring enhancers, often called Ring Guards, Ring Wraps, or Curved Rings  are uniquely designed rings, created to be worn with solitaire diamond rings. The sole purpose of a ring enhancer is to complement a diamond solitaire ring with additional diamonds or gemstones, in order to enhance the size and appearance of a solitaire engagement ring. When worn together, the two rings appear to be a single, multi-stone ring.
Types of diamond-ring enhancers
Popular styles of ring enhancers include wrap rings and insert rings. A Ring Wrap is a single band, contoured to fit around a solitaire diamond ring, displaying additional diamonds on both sides of the center stone. This type of enhancer literally wraps around the solitaire diamond, without completely encircling the center stone. An insert ring is usually a split, double band which provides a gap between the two bands for the diamond solitaire ring to slide into. With this style of enhancer, accent stones frequently completely encircle the center stone.
Function of a Ring Wrap
Wrap rings can serve several purposes. They can be used in addition to a wedding band or can be used as the wedding band itself, creating a coordinated wedding ring set. Wrap rings are sometimes chosen as anniversary gifts or used when renewing wedding vows. In some instances, enhancers have been chosen to wrap around an heirloom solitaire diamond ring, such as a mother’s engagement ring. Generally, these rings are used simply to enhance the appearance of a basic, diamond solitaire ring.
Selecting a ring enhancer
Before selecting the ring enhancer, you should consider what type of enhancer you would like - Ring Guard, Ring Wrap, Curved Ring or other type of ring enhancer.
When selecting a ring enhancer, it is necessary to know both the size and shape of the solitaire diamond worn in conjunction with the enhancer. The shape of the enhancer must conform to the original ring and allow the center stone to fit properly into the wrap or insert. Ring wraps displaying subtle curves are suitable for round diamond center stones. Pointed ring inserts are better suited for marquise or oval shaped diamonds. When selecting a wrap ring, consider choosing a similar metal to that of the engagement ring. In some instances, the wrap ring is soldered to the engagement ring to ensure a snug fit. A big advantage of having both rings made from the same metal type is that the rings will be easier to re-size or repair, if needed. Women with short fingers often use a wedding ring enhancer as their wedding band. Women with long fingers find it easier to wear both a wedding band and a ring enhancer. All of these considerations are important in order for the two rings to blend seamlessly together.
