There is a TON of information out there regarding crystals, their uses, and spirituality. Here are some resources that have helped me navigate this world and learn all about these incredible stones. I will be adding to this list, so be sure to check back for more!
The Crystal Fix is one of my absolute favorite resources and my top recommendation for crystal beginners.
That being said, its easy layout and unique perspective make for a great addition to even a seasoned crystal collector's library. Each entry has a succinct description, a list of key properties, generic information, and uses. It also includes sections on how to use your stones, rituals, and other important information. One thing that really makes this book stand out is its inclusion of crystals for rooms within your home. This is the first book I've found that not only has a section dedicated for the home, but lists the best rooms to display your crystals in on each specific entry. This is a staple for every crystal collector's library.
The Crystal Bible is an absolute necessity for every crystal collector! With over 200 entries on commonly used crystals, it's a treasure trove of information on crystal properties, healing, and crystal placements. Its index of stones by properties makes it incredibly easy to look up what crystals will work best for you and how to make the most of your collection.
