A single stone Solitaire is still the most popular style choice in engagement rings. There are many types of solitaires including tapered, knife-edge, and twist (style of Solitaire in photo). There are some pros and cons to the Solitaire setting. It is the most classic setting out there and pairs well with basically any wedding band but being just metal, its is very susceptible to scratches.
The three-stone setting is one of the most classic settings out there. Known for its simplicity, the two side stones accent the center and help lead your eye towards the center stone.
Graduating Diamond Shank
The purpose of this setting is to lead the eye towards the center diamond. Each side-stone becomes larger as they approach the center.
Halo setting is when there is a row of small diamonds surrounding the center stone. Inevitably, the halo visually adds to the diameter of the center, making it seem larger. The halo also can help cover up some inclisions that otherwise would have been visible from the pavillion of the diamond.
The Double-Halo creates the same effect as the single Halo and then some. Having an extra row of diamonds not only increases the size more, it can add some extra shine to the setting.
This style is know for the band splitting (usually around halfway) leaving a small gap on either side of the center stone.
This style of setting is similar to the split-shank style but the shanks connects at the top toward the center stone. As a result, each side of the setting appears to criss-cross.
The Bypass setting is noticeable by its almost wave-like appearance. The ring curves in opposite directions towards the center stone.
A Vintage-Inspired settings are quite detailed and can sometimes have filigree on the metal.
