*Dichroic combines two Greek roots "di" for two and "chroma" for color, literally meaning two colored. Dichroic glass was first made in Italy in 4th C AD. In the 1950s NASA developed this high tech material as a shield against cosmic radiation. For example, the golden sheen on an astronaut's face shield is a dichroic coating to protect against unfiltered rays. Today glass artists everywhere use this "manmade" gemstone in many formats, especially jewelry for its amazing irridescent rainbow effects.
