How a stone is held
The setting decides how much light reaches the stone, how exposed it is, and whether it will still be there in ten years.
Claw, which shows the most stone and protects it least
Four or six metal claws grip the stone near its widest point and lift it clear of the band. More light reaches it from the sides and underneath than in any other setting, which is why it is the default for a solitaire.
The cost is exposure. The girdle, the stone's widest edge, is left open, and that is where a struck stone chips. Claws also catch on knitwear and bend over years, which is the single most common reason a stone is lost.
Bezel, which is the opposite trade
A rim of metal wraps the stone's edge completely. Less light enters from the side, so the stone can look slightly smaller and slightly darker, and in exchange the vulnerable girdle is entirely covered.
This is the right setting for a stone that fractures rather than merely scratches. Emerald is the obvious case: hard enough at Mohs 7.5 to 8, but heavily included and liable to split along a flaw if struck. Opal and moonstone need it for the same reason.
Channel and flush, for a ring that gets used
Channel setting drops stones between two raised walls of metal, level with or below the band's surface. Flush or gypsy setting sinks a single stone directly into the metal so its table sits level with the surface.
Both keep the whole stone below the ring's highest point, which means nothing catches and nothing takes a direct hit. For a ring worn during manual work, or for anyone who has already lost a stone from a claw setting, this is the practical answer.
Pave, and the maintenance nobody mentions
Pave sets many small stones close together, each held by tiny beads of metal raised from the surface. It produces a continuous sparkle that no single stone achieves.
It also has many more points of failure. Beads wear down, individual stones loosen, and a pave band genuinely does need checking every few years. Ask what the replacement policy is before you buy one.
Matching the setting to the stone
Above Mohs 8, with good toughness, a claw setting is a reasonable risk: diamond, sapphire, ruby and alexandrite all cope. Between 7 and 8, or anything with cleavage, wants a bezel. Below 7, reconsider whether it should be a ring at all rather than a pendant.
