Great Reference Book.
I do have some issues with this book is that Hall does not really reference where he got his information from, I would be happier if this book at better references of source material.
The book also does not go into Moh hardness of the various crystals. This is important as the Moh Harness Scale determines how hard a crystal/gem is and depending on where a crystal falls on the scale, would determine how you would store it as different hardness can damage other crystals when stored together.
He also does not go into depth which crystals are toxic in the individual profiles. He mentions making Gem Elixirs but does not state in the profiles which crystals should be used via the direct method (within water) or indirect method (empty vessel with crystal in it, sitting in another vessel of water), which is very important due to some crystals being toxic.
He mentions methods of cleansing crystals, but does not indicate which crystals should not be cleansed using water (some crystals dissolve/are damaged with water), some crystals get bleached or can cause fires if exposed to the sun, etc.... ( )

This is a comprehensive book on crystals useful for the novice but equally for the more advanced into the usage of crystals ( )
