What is tension setting?
Tension setting is a process of setting diamond, ruby or sapphire by pressure. This process has been developed and patented by Steven Kretchmer. The idea behind the science is that the center stone has no prongs or metal coverage. The stone is almost completely exposed for maximum light return. The science of tension setting calls for a much more complex explanation. Each ring is made specifically for the stone that will be set. The width, depth and weight of the ring will be predicated on the size of the stone you wish to set. The ring is then cast in a “closed” position. A hydraulic machine is then utilized to open the ring, and the stone essentially sets itself. The alloy’s Steven is using are of his own invention. The alloys work as both a hardener and a spring effect. (think spring gold like a money clip) The ring is also put through an annealing process to further harden the product. The finished product secures your stone with 12,000 pounds of pressure per square inch. The numbe
