rails | ˈrālz
noun
Metal edges that line the sides of a melee setting
Rails are used in several types of rings settings to ensure the safe and effective setting of the stone. Rails are commonly used in bright cut and channel settings and are designed to provide a higher level of durability than a prong setting alone could. When selecting a ring or other piece of jewelry with several smaller gemstones in it, it’s important to know the type of setting that’s used and how it was selected. Metal edges in a rail that line the melee setting ensure that there are no issues with durability or protection of the stones in your jewelry. This is one of several types of settings.
