Opals in stock with Australian Opal Mines
“Opal & Gemstone Jewelry Cutting Designing Setting a Step-by-Step Instructional Guide” by Dr Paul B Downing Ph D
The book written by the opal specialist Dr Paul Downing is probably the best instruction book on cutting of opals, setting, buying, the whole deal that I have ever seen. The opal folk of the world are so lucky that he has taken the time to write it. Dr Downing has been an opal dealer, he cuts, sets, sells and knows every aspect of the opal business and has been to the field a number of times in Australia.
