Faith: In Search of the Lost Andesine Mines, Part Two
Author : Richard W. Hughes with Billie Hughes, Wimon Manorotkul and Dana Schorr
The mining of natural red andesine in Tibet has been a subject of controversy. While it is generally acknowledged that large quantities of diffusion-treated andesines entered the world markets starting about 2002, the idea that there might be a source of natural red andesine in Tibet has polarised the gemmological community. This article describes the latest developments, including RWH’s second visit to the Tibetan deposit.
