A solitaire ring is a term that is used to refer to a style of ring that is used to showcase the beauty of a single stone. Solitaire is a type of style that can be used not only for rings but for pendants and earrings as well. Most often, the stone being emphasized is a diamond. Diamond solitaire rings are the type of rings that are usually given as engagement rings. 

Despite the many designs, settings, and styles available, diamond solitaire engagement rings remain one of bride-to-be's most timeless and popular choices. While it may seem deceptively simple, a diamond solitaire can still be a unique ring designed to suite any taste. Simply put, solitaire means one. For an engagement ring, this means the ring has one diamond, without side stones, accent stones, or other gem embellishments. Solitaire engagement rings need not be dull or plain, and for many women, the simple elegance of a single, sparkling stone is the ultimate symbol of the single love that two people share.

There are many choices for engagement ring settings, and while a solitaire ring is by definition excluded from the multiple-setting category, it is not always limited to just those options. Some solitaires, like Prime style's item number 63569, is a solitaire surrounded ever so slightly with accent stones. This makes this solitaire beautifully stand out in an interesting way. The most popular is the prong setting, but the size and number of the prongs can vary to highlight the best features of the stone. Bezel, flush, tension, settings are all appropriate choices because there is only one stone, however, channel settings are not recommended as they may obscure the best qualities of the diamond. http://engagementrings.lovetoknow.com/wiki/Diamond_Solitaire_Engagement_Rings
