I am also interested in the topic below. If you find anything, please forward it to me.
Thanks
: I am interested in "synthetic" or "artificial"
: opals (excluding the plastic impregnated ones and
: "Slocum stone"). Besides the Gilson opals and
: Kyocera "opals", does anyone know of any other
: manufactured "opals". The Russians wrote a book on
: creating opals, but I cannot read Russian, so I don't
: know what they document, but I've heard that they sold
: the process to a company in Japan. Can anyone who is
: knowledgeable in this area clarifiy who exactly is
: manufacturing opals. Thanks.
