● Bezel setting
Bezel settings hold diamonds securely in place with a metal rim that surrounds all sides of the stone, extending slightly above it. Alternatively, some people choose an engagement ring design where the rim encircles only a portion of the diamond. This is referred to as a partial bezel setting or half bezel setting. It still keeps the diamond securely in place but allows more of the diamond to be seen. The bezel setting is a good choice for people with an active lifestyle and may even hide existing chips along the edge of the diamond.
● Prong setting
Prong settings are most commonly used for solitaire engagement rings because more of diamond remains visible when compared to other ring settings. The prong setting forms a basket-like base using three or more metal prongs which are bent over and shaped so that they gently rest against the crown of the diamonds, just past the girdle. Prong ends are mostly rounded; other options are points, V shapes, ovals, flat or even decorative prongs. A prong setting can be short with the diamond resting close to your finger, or tall holding the diamond well above the ring shank. The benefit of the prong setting is that more of the diamond is visible, they are less expensive than more complex settings, and the diamonds are easier to clean. The downside of prong settings is that they offer less protection for the diamond and some prongs tend to snag to clothing or other items.
● Channel set
The channel set another example of popular engagement ring settings. Channel set diamonds are placed into a metal channel on the ring shank and flow in a continuous row. This ring setting does not refer to the center diamond but rather to the side diamonds set in the ring. Side diamonds in a channel set flow down each side of the ring band, giving extra flash to the overall design and enhancing the flash of the ring’s center diamond. Channel set diamonds to make for a beautiful combination together with a bezel setting or a prong setting.
● Invisible setting
The invisible setting is a technique that was developed two centuries ago in France. In the girdle of each diamond, grooves are made that slip into a metal framework below the surface. The metal cannot be seen, so the diamonds sit side-by-side creating a solid surface of diamonds. This ring setting creates the illusion of larger diamonds and is often used by jewelry designers in engagement rings and wedding rings.
