Idriess, Ion L.
- Opals and Sapphires How to Work, Mine, Class, Cut, Polish and Sell Them
Angus & Robertson (Publishers) Ltd., Sydney, NSW, Australia, 1967.
First edition: octavo; hardcover, with gilt spine-titling; 231pp., with many line drawings and 12pp. of monochrome and full-colour plates. Toned and lightly spotted text block edges; mild wear and insect damage to bottom edges of the boards; mild softening of the spine extremities. Dustwrapper is heavily sunned along the spine panel with wear at the edges and flap turns; large chips missing from the spine panel extremities, but no loss to text or images; now backed with white archival-quality paper and professionally protected by superior non-adhesive polypropylene film. Very good. Author's note:- "this book is for you both - the prospector who must make his living from the game, and the family man wondering about that most difficult quest, a holiday rich in interest for the whole family. Even more than keeping all hands eager, the holiday offers a practical chance of winning treasure: a much greater chance than winning the lottery, and with many more prizes - a highly rewarding find of precious opals or sapphires. In fact, such a holiday becomes a genuine treasure hunt. Even if you find nothing, you still return with a treasure of health sweetened by experiences so full of interest that the whole family eagerly plans to give it another go. For each, from Mum and the youngest child to the teenager, can contribute to this hunt for real treasure. And you need no secret map to find it, for in this book simple maps show large proved areas in Australia. In these lie hidden treasure enough to make thousands of families happy and the dyed-in-the wool prospector as well".
