A tension ring is a type of finger ring in which the gemstone is held in place by pressure rather than prongs, a bezel or other mounting. The metal setting is actually spring-loaded to exert pressure onto the gemstone, and tiny etchings/grooves are added to the metal in order to create a shelf for the gemstone’s edges to rest. The gemstone appears to be suspended in the air with nothing holding it in place.
A major difference between tension settings and other settings is that tension settings are only manufactured after they are sold while other settings are often manufactured first and then sold to consumers. There are several reasons for this difference. First, tension settings can not be resized easily as resizing them will remove the spring-loading effect. In cases they can be resized up or down up to 2 sizes but does depend on the design in question. A lot of the time instead of resizing a tension setting, the manufacturer actually has to melt down the old setting and create a new spring-loaded tension setting that is appropriately sized. Second, tension settings are calibrated to the exact specifications of the stone that they will hold, therefore they can not be manufactured until the customer has selected the gem that will go inside. Unlike other settings which can be manufactured ahead of time regardless of the stone that will ultimately be placed inside, each tension setting is designed specifically for the stone it will hold. The tension setting is calibrated by a computer using light to identify the exact places where pressure must be applied on the gemstone in order to avoid fracturing it through uneven pressure distribution.
