Ruby also called Manik is the gemstone linked to Sun, the monarch of all the planets. It is a valuable blood-red colored gemstone. The rich properties of the planet Sun pass on the potential energies to the human. Wearing of the stone enhances self-esteem, communication skills, abundant wealth, sound health and spirituality. The quality of a ruby is determined by the color, cut, clarity and the carat weight. Rubies come from all over the world, but the finest are from Burma. Ruby embedded in gold can be worn by ascendants of Leo, Scorpio, Sagittarius or Aries.
