Tension Set Rings

Tension Set Ring History

Tension set rings were originally introduced in the early 1960's by internationally renowned goldsmith and kinetic jewelry creator Friedrich Becker out of Germany. Mr. Becker employed lateral pressure to hold precious stones between a spring-hardened ring shank.

In the early 1990's tension setting methods were
improved by using a special mixture of heat treated alloys to create spring compression. These tension settings exert 65 to 95 pounds per square millimeter (approximately 12000 pounds per square inch) securely holding the gemstone in place. Only especially hard gemstones may be tension mounted: rubies, sapphires, moissanite, cubic zirconia, and of course diamonds.

Tension Set Ring Longevity

Using the above mentioned special metallurgical method, the tension of the shank can be expected to last for many hundreds of years before some loss of pressure may be experienced. Novori sells only tension set rings that have been manufactured using special heat treated alloys to ensure the longevity of the ring and setting.

Are Tension Set Rings Safe?

The tension setting at first glance can seem a precarious situation for a precious stone, but this is not the case. Due to the high pressure mounting, tension set diamonds and gemstones are considered to be secured as safely, or even safer than, a typical four-prong setting when properly made. Additionally, engineering restrains upon the shank dictate that the mounting must be at least as wide as the gemstone, further protecting the stone from being snagged or chipped. When purchasing a tension set ring, ensure that the manufacturer uses the proper metallurgy techniques as this is a skill only a few craftsmen have mastered. Properly made tension rings cannot be pulled apart by hand but fake tension rings, as sometimes found on internet auction sites, can be pulled apart loosening the stone. Our tension set rings are guaranteed authentic.

Tension Settings Allow Greater Visibility of Your Diamond

The two point pressure method of securing the stone allows for more light to penetrate the diamond than traditional settings. More light entering into the diamond translates into greater brilliance or fire coming from the diamond. It has been said that a tension set ring can enhance the color appearance of your diamond by as much as two color grades. This brilliance in the diamond and unique look of a 'floating diamond' make tension set rings irresistible.
