The setting is how a gemstone is held in metal, and its history runs alongside the history of jewellery itself. The oldest surviving styles are bezels — a band of metal pressed around the stone’s girdle — used since antiquity because they are secure, simple to make, and protect the stone’s edge.
Why prongs took over
Cut gemstones changed everything. Once faceting maximised a stone’s brilliance, setters wanted metal to cover as little of it as possible. The prong setting — small claws of metal holding the stone at its girdle — lets light enter from nearly every angle. It is the standard for solitaire diamonds today precisely because it shows the stone and hides the setting.
The families in between
Between bezel and prong lies a full catalogue: channel settings where stones sit in a row inside walls of metal; pavé where dozens of tiny stones are held by small beads raised from the surface; and tension settings where the metal’s spring holds the stone apparently in mid-air. Each family trades off security, light, cost and surface texture differently.
Why designers care
A designer who understands settings draws jewellery that can actually be made, and prices it honestly: a pavé band is far more labour than a bezel band. Setting styles are covered in the design curriculum at JDMIS and executed at the bench in the metalsmithing foundation course; the gem side of the story is part of GT100 gem and jewellery trade knowledge.
Frequently asked questions
What is the oldest gemstone setting?
The bezel - a band of metal pressed around the stone's girdle - is the oldest surviving setting style, used since antiquity because it is secure, simple to make and protects the stone's edge.
Why did prong settings replace bezels for diamonds?
Once faceting maximised a stone's brilliance, setters wanted metal to cover as little of it as possible. Prongs hold the stone at its girdle and let light enter from nearly every angle, which is why the prong solitaire is the standard for diamonds today.
What is the difference between channel, pave and tension settings?
Channel settings hold stones in a row between walls of metal; pave holds dozens of tiny stones with small beads raised from the surface; tension settings use the metal's spring to hold the stone apparently in mid-air. Each trades off security, light, cost and surface texture differently.
