Andesine Treatment Update
David Federman's article on andesine treatments + John Emmett's viewpoints @ http://www.colored-stone.com/stories/nov08/andesine-copper-diffusion.cfm was educational and insightful. I think Dave was spot on. Instead of relying on traditional gemological methodologies, replication in a lab should be the way to learn more about treatments.
