A must read for anyone who uses and or is interested in crystals- whether you are a lapidary or witch- you will find this book to be both grimoire and text book. Crystal Magic is one of the best books I have read about crystals. Most books on this topic simply name crystals and their properties but this book took it a step further. The first part of the book is about the History and Science of crystals which is absolutely needed if you are going to be working with them. It is fascinating learning about crystals and gemstones in antiquity whether it was in astrology, divination, or medicinal uses. Learning about crystals from a scientific perspective such as their mineral compositions, their crystalline structures, and their formations provides a wealth of information about crystals that help you understand their magical properties even more. This section was not overly scientific, so if you are not a sciencey person, you have nothing to fear about this part of this book. This was extremely useful as we can sometimes forget that at the end of the day, crystals come from the earth. Tips on how to spot fake stones was also very helpful as we want to ensure that we are not simply relying on the placebo effect and that we aren’t supporting fraudulent distributors. I thought the chapter on crystals grids that are based on the crystalline structures of the crystals to be ingenious as I have never come across information about that before. The Compendium of Stones was one of the best I have seen as it also included the history of stones as many books opt not to include that in their descriptions. Two reference guides are also included at the back of the book that list the magical correspondences for the crystals such as ruling deities and planets. Once again this was very helpful. Whether you are a beginner or more advanced crystal practitioner, this book creates a solid foundation in understanding crystals from their historical and geological perspectives. Understanding crystals, gems, and minerals history and compositions creates a deeper and richer appreciation for these marvelous rocks.
