Salt Water -
Most crystals enjoy being immersed in the ocean for an hour or two (place small ones in a mesh bag to avoid loss), after which they can be rinsed in pure water and allowed to dry naturally in pure water to energize.
*If ocean water is not available, a handful of sea salt in purified water works just as well.
Flowing water -
Holding the crystals under a waterfall, in a stream or beneath the kitchen faucet will rapidly cleanse the energies. Allow to dry naturally in the sun.
*soft or friable stones should not be immersed in water and care must be taken not to scratch polished crystals.
*as you cleanse your crystals, hold the intention in your mind that any negative energies will be transmuted into positive ones and that the crystal will be re-energized.
* natural forces, such as the moon, sun, water, or plants are effective purifiers of negative or stale energies.
Salt -
Delicate or friable stones that would be harmed by water can be placed directly into salt or rock salt crystals and left there for a few hours to cleanse themselves.
