Invisible Setting
in·vis·i·ble set·ting | (ˌ)in-ˈvi-zə-bəl se-tiŋ
noun
A style in which rows of square princess cut diamonds or other gemstones rest perfectly flush against one another, within a metal border or frame with no metal separating them
In most standard settings, the prongs or bezels of the setting are visible, even when they are relatively shallow. However, in an invisible setting, the ring is designed to hide the settings completely, ensuring that the rows of square princess cut diamonds or other gemstones set into the ring are perfectly flush with one another. They will sit within a single metal frame and have no metals in between the stones, making them appear as a single connected surface. Each stone has a small channel cut into the base and the rails fit into these grooves to hold them in place. All of this is invisible to the wearer or observer.
