My [...]son loves this book since he is into rocks and minerals. He just told me about a mistake on the cover. I wonder how many other people caught it. The gemstone right below the author's name is not an Azurite, it is a Citrine (Quartz). Maybe the author did this to see how many people catch it. My son is very observant.

I love this book. It's a great resource expecially if you just need a quick guide. The charts are great. Especially nice is the section that shows stones by color.. always color x, usually color x, sometimes color x, etc. So if you are looking for green stones you can find them quickly!

BUT some gemstones I looked up by name, weren't to be found. That left me to go to the internet where I quickly found the gemstone.

Even so, it's a beautiful little book, quick and concise. The photos are gorgeous.
