What are rails in a jewellery setting?
By Jared James · Last updated 21 May 2026
Definition
In jewellery, rails are the parallel metal edges or ridges that line both sides of a channel or melee setting, holding a continuous row of small stones securely in place. The stones sit between the two rails with their girdles gripped by the metal on each side, so there are no individual prongs and the surface of the setting is clean and smooth. Rails are most commonly seen in eternity bands and along the shanks of engagement rings, where a row of diamonds or other gemstones runs between two neat metal lines.
Frequently asked questions
- What is the difference between a rail setting and a channel setting?
- They describe the same style, with rails being the structural element, the metal ridges, and channel setting being the name for the overall technique. The stones sit in the channel, and the rails are the sides of that channel that grip them.
- Are rail-set stones secure?
- Rail settings are generally very secure because the stones are held on both sides along their girdles, with no individual prongs to catch or bend. The risk is that if a stone becomes loose, it can slide along the channel, so any unusual movement should be checked promptly by a jeweller.
- Can rail-set stones be resized?
- Resizing a ring with a full row of rail-set stones running around the band is more complex than resizing a plain shank, because the stone settings need to be adjusted or additional stones added or removed. A skilled jeweller can usually manage it, though the cost is higher.
