hi how can we treat tourmaline from nepal origin?ihave
heard that it is treated for colour enhancement any information?
I am not familiar with any color treatments to tourmaline. As far as I know all tourmaline is naturally colored, but maybe there are new coloring methods for tourmaline that I am not aware of.
Yes They do it, they do the heat treatment in the lab. Then it change color.
Thanks, Jan1. Do you have any supporting evidence that this heat treatment is done?

Interesting. What colors are they once they are heated?
