Well, first of all you need to understand what crystal healing is.
There is a broad array of what this could mean, for example:
The therapeutic application of crystals and gemstones for healing the mental, physical, emotional, and spiritual bodies. See also Gem Therapy and Gemstone-Reiki Therapy.

Now wearing crystals and using them for a therapeutic message are vast different!
My honest answer- I cannot personally recommend just wearing crystals for you. My best friend, ironically her name is Crystal, swears by it.
They have never, however, done a thing for me.
The only time they have had meaning for me is when the stone means something (ex. my birthstone)
Now, learning how to use the different energies for enhancing your life is very different.
