mineral book;"The book of Opals, Wilfred Charles Eyles, 1968

Description

Many books have been written about Opal. Of course, a gemstone as colorful as Opal deserves a visual component. However, before modern layout possibilities(as was the case in the 60's), this book was as good as it gets. Even now, as you can look beyond the black and white photo's, this remains an authoritative work on the topic of opal. A large part describes the rich occurrences in Australia, and is very informative and readable. The book is in good condition as seen.
