The prong setting is the most traditional and popular diamond engagement ring setting type in use, but did you know that the prong setting also comes in several variations? Prong settings can be formed into several interesting shapes, can be doubled, rounded, flattened, and can even be notched into V shapes. These v-shaped prongs are slightly wider than traditional prongs, and are usually placed at the diamond’s corners. Small notches are cut into the end of the prongs, giving it the appearance of the letter V when viewed from above.
This prong variation is especially valued for use with gemstones that have points, like princess cut, marquise, pear shape or heart shape diamonds. The v-prong provides extra protection to those more vulnerable areas of the diamond and are of particular value in securing diamonds in rings- especially engagement rings- which are worn on a daily basis and subjected to more direct stress than diamonds set in pendants or earrings.
A v-prong setting is also helpful to the jeweler in getting a pointed diamond set safely and securely. Pressure must be exerted on the prong and on the diamond in order for it to be tight and secure in the mounting. The construction of the v-prong enables the jeweler to distribute the pressure on both sides of the point and not put too much pressure on the point itself.
While not quite as secure as a full bezel setting which covers the entire perimeter of the stone with a thin rim of metal, v-prongs are more secure than traditional prongs and have the advantage of allowing more of the diamond to show in the mounting. This maximizes the combination of security and light performance of the diamond and allows all fire and brilliance of the diamond to come shining through. This is the choice of a majority of women, especially those with active lifestyles.
Large diamonds also need the extra protection as they tend to stand up higher off the finger and are subject to more contact with the environment. We all know how much celebrities love opulent, dramatic, oversized diamond rings. That’s why you can spot v-prongs securing the likes of Jada Pinkett Smith’s unique three pointed trilliant-cut diamond ring.
