Four-prong and six-prong settings create different balances between stone visibility, outline, redundancy, and visual style.

Four prongs

Four prongs expose more of the stone and can preserve a square or elongated outline. Each prong carries more responsibility, so placement and construction are important.

Six prongs

Six prongs add more contact points and can provide greater redundancy if one prong is damaged. They may make a round stone look slightly rounder and can cover more of the edge.

More prongs do not guarantee better security

Prong thickness, metal, seat quality, stone girdle, basket support, wear, and maintenance matter as much as count.

Shape changes the answer

Four well-placed prongs may suit radiant, cushion, emerald, or princess outlines, while six are common for round and oval stones. Pointed shapes may need a V-prong or other specialized protection rather than simply adding more standard prongs.
