I also included a scanned image of the front cover in case you, like me, remembers the cover better than the title. Keep in mind covers sometimes change too. Humm, I have two favorites along mineralogy lines, and one favorite for gemstones. I have loaned out at least three copies of the book and never got them back. The photographs are clean an well done.
Environmental data is perhaps the weakest.
There are often two or more photo examples per mineral. There are just over 500 minerals identified. Looking up minerals requires extensive use of the index unless you know the streak color and hardness. The information provided is excellent and the photographs offer several good images of each material. There are well over 1000 photos of different specimens and all are well lighted and clear.
