There are many who question the basic premise that crystals can "channel" energy, claiming that there is no proof that such energies exist. The only argument I have to refute that is that at one point in time, we did not know about electrical energy, X-rays, gamma rays, ultra-violet rays, nuclear energy and all the other subatomic particles that science has found in recent years. When I was going to school, we were taught that the electrons and positrons and neutrons were the smallest subatomic particles. Now science has found subatomic particles that make electrons look as big as the earth compared to the moon. So the fact that science has not yet created a piece of machinery to measure that energy does not negate the fact that such energy exists, anymore than man's ignorance of nuclear energy negated the fact that it fuels the sun.
Crystals are not only associated with different energies, but with different parts of the body and different ailments (as "aids" for healing that ailment). There are countless books that list what each crystal is for and there is no unanimous agreement on exactly what each crystal can do. The more recognized crystals, like amethyst and rose quartz, have a much more consistent listing among various books because they are the more "popular" ones and their abilities have been explored more extensively than some of the "newer" crystals.
While the books you might find will give certain uses for certain crystals, the most important thing is how you feel when you pick up a crystal you are thinking of purchasing. If you allow yourself to feel the stone, it will tell you what you need to know about when to use it. I have a personal attraction to rainbow obsidian, black tourmaline, peridot and malachite. There is something about these stones that calls to me. You will have to find your own stones that call to you. Books can give you a place to start, but it comes down to what feels right for you. Below, I've listed some of the more commonly used stones and their uses.
