Although three-stone rings tend to be more expensive than solitaires, they do offer much greater potential for variety. Each stone is rife with symbolism, with a rock representing the past, present and future of the couple's relationship. Three-stone settings can feature two smaller stones on either side of one dominant stone, or a groom might choose to select three diamonds of similar size.
Three-stone rings are glamorous and certainly up the sparkle ante. A ring-building tool, such as the one offered by online jewelry retailer Blue Nile, allows you to build your own three-stone ring by choosing the setting, center stone and side stones. You can even specify the carat, clarity and cut you want.
