We fiftyish divas have another reason to celebrate wearing jewelry.  With a bit of thought toward the type of benefit we would like, our next shopping expedition for jewelry could be a bit more focused toward providing us with an ongoing, positive influence.  The term crystal includes gemstones or precious stones and semi-precious stones.  Crystals can be worn as pendants or as rings.  A six-pointed crystal (many are long, polished stones with six sides and often have a pointed or rounded end) balances the upper and lower chakras (energy centers) and also balances and strengthens the upper, middle and lower sections of the aura.  As a pendant, a crystal is preferably worn between the heart and the throat.  As a ring, it is better to wear the crystal on the little finger or the middle finger, either on the left or right hand.  Garnet is preferably worn on the right hand and is used for strengthening the aura and for psychic self-defense.  People who are pessimistic or rather negative should not wear it because they tend to attract misfortune.  However, if worn by people who are wholesome and optimistic, garnet tends to attract good luck.  Citrine is good for psychic self-defense.  It should be worn also on the right hand.  Green tourmaline or emerald is recommended for healers, physicians and psychotherapists.  It should be worn on the right hand.  Diamond is a very powerful crystal for psychic self-defense and is preferably worn on the right hand.  Diamonds with inclusions, slightly yellow diamonds or a cluster of small diamonds on a ring will do.  The cheaper ones will provide more or less the same degree of protection as will expensive diamonds.  The crystal should be cleansed before wearing it as a pendant or ring.  One of the easiest methods is to wash the crystal with soap in running water for about a minute or more.  You may also use the fingers to rub it under running water with mind intent to cleanse it of all impurities.  Another method is to use alcohol to cleanse the crystal.  Source: Practical Psychic Self-Defense for Home and Office by Master Choa Kok Sui.
