Yes Catherine, I am referring to Chrome Tourmaline, unless someone else in the forum has any other knowledge in regard to heating Chrome Tourmaline but all indications are heating does not change the colour??? Once again with so many things being tested someone may come up with something. in the past 3 or 4 years we have seen cobalt treated sapphire, heated and glass filled ruby now green & yellow sapphire as well, Beryllium treated sapphire and ruby etc.
