GEMSTONES FOR SUN

Ruby is the gemstone recommended to strengthen a good Sun . Courage and willpower may be increased by wearing a good ruby. It will increase vitality and the ability to perceive things in a truthful manner. It can help in developing spiritual insight or looking within towards spiritual realisation.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. If in the horoscope the ascendant (rising sign) is Capricorn, Pisces, or Virgo, it is recommended in general that one of the substitute gems of Ruby be utilised instead. Red tourmaline, called rubellite, or red garnet may be substituted for ruby and will give the same effects, although with somewhat less potency.A ruby should be of an even colour ranging from deep-red to other tones depending on occupation. 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 should wear a slightly orange-red colour. An artist, clercial person, or skilled or unskilled labourer would wear a ruby of a dark purple-red colour.The major sources of rubies are Thailand, Burma, Laos, Cambodia, India, Sri Lanka, Africa and Afghanistan.
