The Diamond Tension Ring
was originally introduced in Germany in 1979 as a new way of setting a precious stone. The single brilliant and seemingly floating diamond sits firmly in specially cut tiny grooves in the ring and is exposed to a tremendous amount of pressure per square millimeter. The lateral pressure holds the gemstone within a spring hardened ring shank. This is why only the hardest gemstones can be tension set: diamonds, sapphires and rubies. Light enters the diamond from all angles and maximizes its brilliance. Each ring is a feat of engineering and exquisite design.
The SILVERBRIDGE 
tension rings are startling in their elegance and simplicity. The diamonds we use are of a natural brilliance and superb clarity, colourless, and certified. All tension rings are manufactured in accord with very high standards of craftsmanship and technical quality. They are undoubtedly wearable in everyday situations and perform very well when cared for properly.
Each SILVERBRIDGE tension ring style can be customized, you can choose diamonds of various dimensions or you can supply a heirloom diamond of your own. Your ring will be custom made with utmost attention to detail like all the other pieces in our collection, based on a tradition of fine craftsmanship and contemporary jewellery design.
