There are many books you can read or people you can ask about your special stone and its benefits for you. Always treat your stones with love and respect, thanking and cleansing them after working with or wearing them. A quick and easy way to cleanse stones is with incense which is safe for all stones and minerals, whereas water is not. As you hold the stone in the smoke, ask that it be cleansed of all disharmony it has taken on in an effort to protect you and your environment. Ask that it be filled with unconditional love and to continue working with you for your mutual evolvement.
Quartz crystals are a good starting point for the beginner.
There are several types and colours of quartz. All have the basic qualities of Clear Quartz, then added qualities due to the differing minerals that give them their colour vibrations. Clear Quartz contains piezoelectric and pyroelectric properties which support amplification, focusing, storing, transfer and transformation of energy. Seen by many crystal therapists as a bridge between our mental and physical dimensions, it aids our connection with angels, guides, master teachers and healers. It can be used anywhere on the body at any time for any problem except for tumours.
