Wands are a wonderful energetic healing tool. Depending on the gemstone that the wand is made of, the healing qualities will vary. Healers often use intuition when choosing to use a particular wand on a particular person. Sensitive healers can feel the energy eminating from the wand and this also helps in the selection process. For most people, I think it is best to choose whatever you feel attracted to. If it holds a visual appeal, there is likely some kind of energetic connection for you.
