I ve recently aquired an amount of untreated Tanzanite and tsavorite. upon routine heat treating the Tanzanite i inadvertenly heated a small piece (8ct) of Tsavorite along with it.
The piece of intense green tsavorite became a neon green/blue after accidental heat treatment. Is this a correct outcome? or have I got a imitation rough of tsavorite?

please reply with suggestions including comical if apprpriate!

many thanks

Richard
