I follow the author on YouTube and enjoy her archive of crystal videos (some dating back 4+ years), including her latest series of live channeling. This book is different from the other resources so far which have read like encyclopedias or dictionaries which provide definitions and meanings; her book has that too, if you want a quick reference, flip to the appendix. What this has which I like are that her chapters (organized by intention: love, health, wealth, etc.) start with personal anecdotes of some clients' real-life problems which they'd come to her for healing, and she shares the crystal prescription/ healing regimen that helped them through it. It's rarely just one crystal, but multiple, and sometimes in waves: e.g. First sessions to clear out blocks or debris, before the succeeding ones to start working on deeper issues. It's a good way to learn which crystals can combine well together to achieve the desired effect.
The writing style is friendly, easy to read. I went through it once already but I'm flipping through it again because it's been giving me great ideas for jewelry designs. If you're into making your own crystal jewelry, it wouldn't hurt to make sure the design is harmonious, not just to the eye but also in terms of energy, right?
The only reason I haven't given it five stars is because it doesn't have that many stones. I was searching for some and couldn't find: iolite, amber, ametrine, dumortierite, lapis lazuli, prehnite, peridot, larimar, etc.
Although that can be a good thing especially for the beginner, who might only have access to the more easily available and inexpensive crystals, it's a shame because I'd have loved to read her thoughts and experiences working with those stones.
update: a few weeks later - I find myself coming back to this book again and again for the crystal combinations. Great reference! I hope a volume 2 or revised version comes out with more stones. 4.5 stars.
