Four Prongs vs Six Prongs

Yes, all engagement rings have prongs. A prong is a little metal that grips your precious diamond tightly, holding it in place. Prongs can be round, pointed, flat or v-shaped (latter suitable for princess cut stones). Further, you can choose between four prongs or six prongs.
What is the main difference between four prongs and six prongs?
An engagement ring with four prongs spaced evenly apart on a round diamond, it will create a square appearance as the prongs are set on “separate corners.” Four prongs are obvious choices if your center diamond is a princess or emerald shape. A benefit of a four prong setting is lesser around of metal coverage around the diamond. This will allow more light to enter the diamond and allows the diamond to maximize its brilliance.
In a six prong setting, the prongs are evenly placed on a round diamond which, for a hexagonal shape. The individual prongs are generally lighter and thinner in order to minimize the area where the prongs cover the diamond. A six prong setting will allow your diamond look rounder and in some cases bigger.
There is not an obvious choice for which prong setting to go with. It depends on your personality and taste. A four prong engagement ring setting is perfect for someone that wants to show off their diamond as much as they can. This is done by minimizing the metal around your precious diamonds. Whereas, the six prong setting will give your diamond a rounder look  and offering more security with the extra two prongs around your precious stone.
