All the religions of the world mention the use of crystals or gemstones for protection, healing and contemplation, and as being a guide through the development of a person's individuality on a spiritual and material plane.

In every world's nation there has been and still exist experts who know the "secret" relationship between humans and stones whether through scientific methods, or through insight and identification with the matter.

The effects and the use of crystals or gemstones are often mentioned in the astrology of the East and the West, and this science connects crystals and gemstones with the influence of planets and stars affecting the whole of living with the spectrum of their radiation.

Determining the appropriate crystal or gemstone through the use of Astrology depends on the position of planets at the moment of birth and if the influence of a certain planet is considered "disturbing", it is recommended that a person wears a certain crystal or gemstone to diminish or neutralise these negative influences.

Astrologers emphasize that since each crystal and gemstone is unique, the precise choice has to be made.
The real value of an expert is the capability to recognise and divide the nature, shape and meaning of the crystal or gemstone from it's emitting vibration and energy; the energy that actually creates this "union" with the person who wears it.

Possible effects range from strong to subtle ones, and every effect affects the psychological as well as physical plane; knowledge of which is familiar to the expert person and could be passed on to you, too.

The birth-stone's effects in individuals

Magnetism: After the stabilisation of energy, a healthy relationship (polarity) occurs between the body cells.
Psychic Influence: Helps in realising inner peace and stable directed consciousness.
Fitness: Becouse of before mentioned effects, a condition of energy conservation is attained, resulting in increase of physical energy (body warmth).
Protection: If performs a protection from psychic and mental influences.
Health: Helps in maintaining the physical immunity and in neutralising any existing difficulties.
Self-help: Placing your birth-stone on a troubled area, in the contact with the skin, you are performing self-help which can in a short time-span (5-10 min.) neutralise mild pains.

Directions: It is undesirable to let any other person but you touch your birthstone. You can give help to another person only in cases of emergency. It is advised to keep the stone with you at all times. If you are separated from it for longer than 21 days there is a possibility that the stone will change it's vibration, and thereby break it's "contact" with you. In such a case, consult the expert.

Jyotish gems have been prescribed by Vedic Astrologers for many centuries to combat the negative influences of the planets. Each planet has a corresponding gem. In India, the proper method of determining the right gem is to do a lifetime chart for the querent based on birth information. The proper stone is then prescribed. The stone must be worn in a ring or bracelet.
