A very useful guide
Format: Kindle
I gave the book to my dad since he is interested in these topics. What he liked the most was the large amount of information it contains, such as information on semi-precious stones.

Don't recommend.
Format: Paperback, Format: Paperback
Not at all what I was expecting. It must have been self or independently published. Returned. I will definitely be scrutinizing my next book purchase on this subject to more stringently. Also, Not that I care but claiming to be "7 books in one" is a false claim. But I kind of figured that before I purchased it. Its just bad.
Big turn offs for me.
-No/poor editing.
-Page formatting makes my eyes bleed.
-The font tries too hard to be fun--especially for an instructional book.
-pages feel cheap.
-image quality is abysmal.
- none of the information I was looking for and lots of information I wasnt.
