Tension Setting
The stone appears to float between two ends of the band, held only by the compressive force of the metal.
Definition
In a tension setting, the diamond is held in place by the pressure (tension) of the metal band pushing against the stone from both sides. A small groove is precisely calibrated to grip the girdle. The result is a striking illusion of a floating diamond with no visible support structure. Modern tension settings often include a hidden rail or channel for added security.
Why It Matters for Ring Design
Tension settings create a dramatic, contemporary look that appeals to design-forward clients. However, they require specific metals with sufficient spring strength (platinum or certain gold alloys) and careful sizing — resizing is often not possible without replacing the entire setting.
