Flush Setting
flush set·ting | ˈfləsh se-tiŋ
noun
A jewelry setting in which a stone is set within a metal hole and metal is applied above the girdle
A flush setting is a type of setting for a gemstone, in which the upper plane of the gemstone and the metal around it are close to flush with one another. This is considered the most durable stone setting because the stone is secured from every side and none of it protrudes from the piece to get caught or potentially chipped on outside surfaces. Without prongs or other elements of a raised setting, it is less likely to get caught on anything, torn, bent, or otherwise impacted by outside factors. Often, a ring might have a number of flush gems in the band while a single gemstone remains raised in a pronged setting.
