Crystals healing and where to place them : 

Crystal healing is a term that applies to a certain type of therapy which involves placing gem stones on your body or in nearby places to help draw out negative energy. Crystals have existed on earth for millions of years. They're a tool which work with your energy field to absorb, focus and direct energies.

Keep them in a bag or pocket, but they also work well when tucked around the house.

A great place to put crystals is on your nightstand or under your mattress because you can feel their energy while you sleep or behind your computer at work. It's best to keep them in spots where you're around them for a substantial amount of the day.

Every few weeks  cleanse them in water  charge them with their own natural energies, either on a full moon or in sunlight. If you keep them in the house all day they can become disconnected from their natural sources of energy.
