Gems are considered to be the best for strengthening the positive influence of planets. They intensify the rays of the planets they represent. Each gemstone is specific to a certain planet and takes positive traits of that planet. Since ancient times, people have sensed powerful energies emanating from gemstones and crystals and felt their ability to bring good fortune and ward off evil. These beautiful, coloured, natural gemstones are believed to provide supernatural powers that will protect the wearer from illness, misfortune and danger.
