Working alongside his wife, Alma, in an old schoolhouse-turned studio in New York's tranquil Hudson Valley, Steven Kretchmer earned numerous patents for his inventions in metal and alloy, including his new product line, Polarium - a permanently polarized platinum alloy that acts like a magnet. Steven Kretchmer's invention, the "Tension Set", is the ring that put him on the world map as more than a jeweler with a metallurgical bent. Kretchmer's tension set is the product of many years of countless experiments and unique design prowess. The magic of an authentic Steven Kretchmer tension setting is the 12,000 pounds per square inch integrated fitted mounting that secures your precious gem forever. Made using special alloys and a patented heat treatment process, which allows the metal to be strong yet elastic, this setting allows the maximum amount of light to reach the stone for excellent fire and brilliance.
