Prong styles explained: four-prong, six-prong, claw and tab
Prongs are the small metal arms that hold a stone. Their number, shape and thickness all affect how secure the stone is, and how much of it you see.
Four prongs vs six prongs
- Four prongs show more of the stone and are a classic choice.
- Six prongs hold the stone in more places, so the stone is held by more points if one prong wears.
Shapes of the prong tip
- Round or ball tips are comfortable and less likely to catch on clothes.
- Claw or pointed tips are slim and sharp-looking, and they sit lightly over the stone.
- Tab prongs are flat and wide, common on emerald and cushion cuts.
Protecting corners and points
Stones with points or corners, such as marquise, pear and emerald, need prongs shaped to cover those weak spots. A V-shaped prong is often used at a point.
What to check in CAD
- Prong thickness: strong enough to hold, slim enough to look refined, commonly around 0.8 to 1.0 mm. Confirm with your caster.
- How far each prong overlaps the stone
- Whether the setter can reach the prongs to close them

Frequently asked questions
Are six prongs always better?
Not always. They are more secure, but they cover more of the stone. The right choice depends on the stone and how the ring will be worn.
Do prongs wear out?
Yes, over time. Regular checks by a jeweller are advised, especially for rings worn every day.
