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. If your crystal came in one of the brocade pouches, they are all natural. If your crystal 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 place it 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, do it in running water. In a pinch, this could just be water running from a faucet. If in a stream, river or creek, leave the crystal under the water for at least twenty-four hours. It is always best not to share your crystal with anyone, even your mate.
