What is a shared prong setting?

Definition
A shared prong setting is a style of multi-stone setting where each prong is positioned between two adjacent gemstones and holds both simultaneously, one on each side. This means you need fewer prongs than individual settings would require, which keeps the metal minimal and lets more light into each stone. Shared prong settings are particularly popular in eternity and half-eternity bands, where they allow a continuous row of diamonds or gemstones to sit closely together with a clean, open appearance and excellent sparkle.
Frequently asked questions
- What is the difference between shared prong and individual prong settings?
- In an individual prong setting each stone has its own set of prongs holding only that stone. In a shared prong setting, the prong sits between two stones and grips both at once, so fewer total prongs are needed. The result is a lighter, more transparent look with the stones sitting closer together.
- Are shared prong settings secure?
- Yes, when well-made they are secure, though because each prong is doing double duty, damage to one prong can potentially affect two stones rather than one. It is sensible to have shared prong bands checked periodically by a jeweller to ensure all prongs remain tight and no stone has shifted.
- What rings use shared prong settings?
- Shared prong is the standard setting style for eternity and half-eternity bands with round brilliant diamonds, though it also appears in wedding bands with other stone shapes. The minimal metal and open look make it popular for stacking alongside a solitaire engagement ring.
