Prong Setting
/prawng/
Definition
A setting technique using small metal claws (typically 4 or 6) to grip and elevate a gemstone above the ring band, maximizing light exposure and visual prominence.
Prong settings — also called claw settings — use individual metal projections to hold a gemstone in place by gripping its girdle or just below the crown. The most common configurations are four-prong (more of the stone visible, slightly less secure) and six-prong (more secure, slightly more coverage). Prong settings allow maximum light to enter and exit the stone from all angles, which is why they are the standard choice for diamond solitaire engagement rings. The Tiffany setting, introduced in 1886, is the most iconic prong design — a six-prong head elevated on a knife-edge band. Prongs require periodic inspection as they can bend, loosen, or wear down over time.
Usage in the Trade
Prong settings dominate engagement ring design, especially for round brilliant diamonds. They are used for center stones in solitaire, three-stone, and halo ring designs, as well as in stud earrings and pendant necklaces.
