Lucky Stone / Gems : Ruby

It is connected with planet Sun. The metal with which it associates is gold. It rules over eyes and bone system in our body. It can be worn by those whose ascendant sign is Aries, Scorpio and Sagittarius. It should be worn in the ring finger.
One’s courage and will power may be increased by wearing ruby, and it will increase vitality and the ability to perceive things in a true and correct manner. It can help in developing spiritual insight, or looking within toward spiritual realization.
On the physical side, it may strengthen the heart and help digestion and metabolism. It should be noted that rubies are so powerful that if worn by the wrong person they may cause physical or mental imbalances in the categories governed by the Sun. Red tourmaline, called rubellite, or red spinel may be substituted for ruby and will give the same effects, although with somewhat less strength.
Rubies range from deep red to other tones depending on occupation or effects desired. A teacher, intellectual, or priest should wear a ruby of a pinkish-red color. A ruler, administrator, or military officer should have a blood red color ruby. A merchant of any goods or produce, or one involved with banking or monetary instruments can wear a slightly pinkish-red to slightly orange-red color or can also wear the blood-red color. An artist, clerical person, or skilled or unskilled laborer would wear a ruby of a darker purple-red color.
The major sources of rubies are Thailand, Burma, Laos, Cambodia, India, Sri Lanka, Africa and Afghanistan.
