Astrology for Women Gemology Prescribing a gemstone to ward off any planetary afflictions in a birth chart of any person is a very delicate procedure. In order to prescribe any gem to any individual his or her birth chart should be thoroughly examined to see which of the malefic planets are in chidra bhavas or are functional malefic (malefic on account of the lordship of inauspicious house i.e., the 6th, 8th and 12th). If we will prescribe a stone for any of such planets, we will be only strengthening and accelerating their malefic tendencies. Therefore, the stones associated with the planets that are functional malefic for an individual should never be recommended. Planet Stone In Astrological works, the nine planets have been assigned nine different gemstones. According to the classical famous astrological work 'Jatak Parijat' we can divide the planets and their stones as follows:

Home Gemmology Gemmology What Is a Gemstone? A gemstone is a collective term for all ornamental stones that possess the following attributes: Beauty Rarity Durability Demand Tradition Portability Gemstones have three basic origins: Inorganic: minerals. Organic: formed from living organisms. Man-made: formed in a laboratory environment. WHAT IS A MINERAL ? A mineral can be defined as being of inorganic origin with a definite chemical composition, physical properties which are relatively constant and a crystalline structure. In mineralogy, there are several thousand minerals listed but only about 100 have been cut as gemstones with fewer than 50 having the necessary qualities to be truly classed as "Gemstones". WHAT IS A ROCK ? A rock can be defined as any mineral or mixture of minerals that makes up an important part of the earth's crust. Examples: Granite (Feldspar, Quartz and Mica) Lapis Lazuli: (Lazurite, Sodalite, Calcite and Pyrite) There are three main groups of rocks, namely: Igneous - Rock solidified from the molten magma either within the earth or at its surface. Sedimentary - Formed from the fine deposits of sand, grit and clay which were eroded from ancient pre-existing rocks by the actions of wind, rain and flowing water to form alluvial deposits.

There are also man-made stones which do not have a natural counterpart and simulants which may resemble the appearance of a natural stone but differ greatly in all other aspects. The French chemist Fremy produced the first commercial synthetic gemstones in 1877. These were small ruby crystals and were grown by fusing together a mixture containing alumina in a clay crucible, the process taking some eight days. These were termed "Reconstructed Rubies". In 1885, larger "Synthetic" rubies made their appearance. At first, it was thought that these larger rubies were also products of the earlier fusion method used in 1877. More recent analysis, provides proof that these were in fact products of an early form of "Flame fusion" using alumina powder rather than fragments of ruby. Today, synthetic gemstones are produced by a variety of methods including:-
