Abstract
During the investigation of red andesine from Tibet, several samples of what appeared to be andesine in matrix were provided. This article documents the examination of these specimens with the goal of proving or disproving their authenticity. Microscopic examination, Raman, LA-ICP-MS and ATR were used and the results are presented. The findings strongly suggest these specimens are manufactured.
