The reason a crystal may need cleansing is that it was handled by someone whose personality (vibrations) do not agree with the crystal's. It is always best not to share your crystal with anyone, even your mate. Caring for your crystal (s) is easy. Treat it as you would any new addition to your family. Remember it has been literally torn apart from its family of other crystals. Keep it wrapped in any natural material such as silk, cotton, wool, or leather.
f your crystal came in one of the brocade pouches, they are all natural. If it came in one of the velour pouches, it may have been sewn with synthetic thread or the velour itself may be a synthetic material. It is also a good idea to put your crystal in a place where it can get direct sunlight every few months. Crystals love the warm bright sunshine and are recharged by it.

It should not be necessary to cleanse your crystal, but if you feel it needs to be cleansed, the following cleansing methods have found to be very successful:

Water is a wonderful universal cleanser. Hold your stone under cold flowing water from the tap (cold or lukewarm water only. Never use hot water) Always allow your stone to dry naturally - preferably from the rays of the sun! If, however, there is little or no sun around, then you should allow your stone to dry in the warmth within your home.

Immerse your stone in salt water for several hours or bury the stone under the earth in your garden. Our planet Earth consists of at least one third quartz and the very strong and powerful magnetic energy field in the actual earth will 'cleanse' your stone of all its negativity very effectively.

Place your stone on a large quartz crystal cluster for a few hours. The very strong crystalline energies present within the cluster will soon neutralize any negative energies to be found within your stone.
