Tension Setting Info


What is "Tension Set"?

"Tension setting" is believed to have been started in Europe, possibly Germany, about 30 years ago. In tension set rings, the stone or gem is held in place only by tension or spring of the metal band. Initially gold and/or silver were used in the manufacturing. However as gold and silver are relatively soft material and in order to achieve the required tension the bands had to be made fairly thick , resulting in a chunky and heavy ring.

Today, you will find tension set rings using platinum, gold, stainless steel and titanium. The tension has to be just right, if it too loose the stone will fall out and if too tight the stone will crack. For this reason, you should only buy tension set rings only from an experienced manufacturer and one that will guarantee their designs. With tension setting, light is allowed to pass through the stone unimpeded resulting in a more brilliant stone. Tension setting also allows a flatter profile for a high tech look. Due to the way the ring is made, the ring generally cannot be re-sized.


About our Tension Set Rings

Each our tension set rings is engineered to exacting specifications with a seat cut into the side to hold the stone and a carefully calculated gap for the size stone selected for that design. Every style is engineered to maximize the security of the setting.

As far as the tension sets go, our titanium has a tensile strength of between 30,000 and 45,000 pounds per square inch. This is at least 100 times more than most gold, silver or platinum tension set rings. Additionally titanium has a far greater memory than the aforementioned metals.

Due to the nature of this process it is important that each stone is uniformly cut, at least 7.5 on the hardness scale and relatively free of internal fractures or inclusions. It is quite possible that some structural irregularities are undetected and result in chipping. This is a very rare occurrence (less than 1%) and result in the stone becoming loose.
