Handcrafted Stainless Steel The idea to use thermosensitive elements in jewelry first arose from the American jeweler Marvin Wernick in 1974 after reading a magazine article about the use of liquid crystal elements in medical thermometers. He found a compound that changed color from black to green, blue and deep blue in the range of 32–38 °C and in January 1975 developed a technique for using it in pendants and rings. It was a great sensation, but by December of the same year the fad had run its course. Handcrafted from stainless steel.
