Gemology - Personalized Gemstone Recommendations by Sheelaa M Bajaj

Gemology is the science dealing with natural and artificial gemstone materials. A natural gemstone is a mineral, stone, or organic matter that can be cut and polished or otherwise treated for use as jewelry. A precious gemstone has beauty, durability, and rarity, whereas a semiprecious gemstone has only one or two of these qualities.

A gem is a gemstone that has been cut and polished. Diamond, corundum (ruby and sapphire), beryl (emerald and aquamarine), topaz, and opal are generally classed as precious stones and all other gemstones are categorized as semiprecious. Gemstones occur in most major geological environments and are further categorized as mineral gemstones and organic gemstones. Mineral gemstones are more durable than organic gemstones.

Gems are the storehouse of plenty of energy that helps human beings to overcome various hurdles that will be faced in our everyday life. Gemstones are prescribed in two different forms one according to the month commonly known as Birthstones and other according to the horoscope (Kundali).

Gemology According to Planets

The Science of Gemstone astrology is based on the fact that cosmic forces of planets rule human body and life. The cosmic arrangement of our birth chart defines how much of a help we will get from fortune in the course of our lives. Our birth chart and the position of planets make our physical, intellectual, emotional, spiritual, and even karmic self and are the key deciding factor of the gemstone one should wear.

The birth chart is made up of some genuine dominant planets and some that are actually weak. Hence Gemstones are used to enhance particular weak planet thereby removing the malefic effect.

Gemstone should be recommended on the basis of the positioning of nine planets, their chakras, and placement of ascendant and trine on the birth-chart of a person. An astrologer thoroughly evaluates the positioning of each and every planet during the birth of a person and recommends gemstones.

There are nine gemstones in correspondence with nine planets and each of them carries special characteristics to offer to the ascendants of their respective planets. It is always advisable to wear the gemstone by consulting an astrologer and follow all necessary rituals to achieve maximum benefit. As each gemstone corresponds to respective planet one can wear multiple gemstones by verifying the compatibility as wearing wrong gemstones will yield awful results
