    Steven Kretchmer: With a Tension-Set™ by Kretchmer, the strength of the entire setting itself secures the stone in place by a compression force of 12,000 pounds per square inch, not just with wires as in prong settings. This type of mounting also exposes the gemstone to more light, and brings out the brilliance and colors that are often hidden by prongs or bezels. Tension-set™ jewelry is especially comfortable to wear, and has no prongs that scratch or catch on clothing. It is fundamentally stronger and more durable than traditional settings, and is built to endure everyday use more successfully. Impacted by unusual force, a prong-mounted stone can shift and loosen when the prongs bend, but a Tension-Set™ stone is held by pressure, secured into the seat by specially heat-treated precious metal alloys, and needs no routine tightening or maintenance. Kretchmer Tension Settings are the only patented tension settings in the world.
