Since ancient times, our ancestors have known how to use, care for and choose their gem or crystal. It was experience and knowledge that was passed down from generation to generation, or they were passed down from master to apprentice. Living in harmony with nature, our ancestors found answers to questions and passed on this knowledge. But only a select few knew more than others and knew how to use them.

We have written this book to serve as your assistant. It describes how to choose the right gem, their varieties and how to distinguish them from another gem and from a fake, their healing properties and metaphysical effects on humans. So that you can improve your life and change the environment around you.
