Each of the signs of the zodiac rules
a particular
gemstone,
a fact which has been widely used in jewelry from time
immemorial. Conversely, each gem conducts the energies
of the particular sign or planet with which it is
sympathetic. Wearing the
stone
of your sign will focus the energies of the sign through
the gem, enabling their expression in your daily life.
The energy of the sign is channeled through the planet
placed there (usually the Sun, Moon, or planetary
ruler); this energy is expressed and focused through the
corresponding gem.
