Re: heat treaments for color changing
One more thing. When polishing Tiger Eye, always polish with the fibers. My understanding is that the fibers are hollow. Microscopically speaking. If you polish into the fibers they can collect material and the finished stone will be less than desireable. You may already know this, just thought that if you didn't it is good to know.
