Gemitech - Thermochromic behavior - Chameleon diamond Chameleon diamonds typically change color from greyish-green to yellow when they are heated (thermochromic behaviour) or kept in the dark (photochromic behaviour). Those diamonds are type Ia with A aggregates largely dominating the nitrogen speciation. They contain moderate to high amounts of hydrogen, in addition to some isolated nitrogen and traces of nickel. Temperature seen here in the background is in Celsius degrees (ref. E. Fritsch, L. Massi, GR Rossman, T. Hainschwang, S. Jobic, R. Dessapt (2007) Thermochromic and photochromic behaviour of "chameleon" diamonds, Diamond & Related Materials 16 (2007) 401--408).
