Four prong or six prong that is the question. Many jewelry companies only use six prong heads to hold your diamond. We have always suggested four prong settings.
Main chain jewelry stores suggest six prong heads. At Richard Dolgin Private Jeweler we have always preferred the looks and durability of a four prong setting. Many times the suggestion for a six prong head is made because there are so many unknowns when someone else is going to set a diamond. Choosing more prongs seems a safer bet when an inexperienced jeweler is doing the setting work. For example, over cutting the seat that the diamond sits in could lead to prongs breaking easily and loosing your diamond. When a Master Jeweler is setting your diamond, they know the proper angles of the prongs and how to cut the seat the diamond sits in properly. The prongs on a six prong head are actually thinner and lighter than those on a four prong head. The four prong head is actually heavier and because of the angles of the prongs very secure. If a four prong head is installed and set properly it is as secure as a six prong head.
In most cases, the intent of the prong setting is to make the diamond the focal point of the ring, as if it were suspended above the surface. More prongs can appear as a mass of metal, overshadowing the diamond and style features of the ring. Truly a case that less is more.
