Prescribing
a gemstone to ward off any planetary afflictions in a birth chart of
any person is a very delicate procedure. The prescription of a gem
depends largely on the astrologer's keen observation and intuition.
The stone must be match the qualities of the person. The stone must
'arouse' the qualities that a person needs to become success.
Ideally, gems should be worn on the correct
finger, should be set in the correct metal, and should be the
correct weight. They will have the best effect if they are also worn
on the correct day and at the correct time of day. At least the
installation of the gems should be performed on the correct day, and
proper mantras should be chanted when they are first put on. It is
best if the gem’s wearer, him or herself, chants the mantras.
It is important to clean gems before
wearing them. They can be cleaned by running water over them for six
to eight hours, by burying them overnight in the earth and then
rinsing them with clean water in the morning, by placing them in a
candle flame, or by placing them in direct sunlight. They can also
be purified by being placed next to a crystal quartz.
