The stones are often set within gold or silver jewellery with a ruby as the centrepiece representing the Sun. Each additional stone around the ruby then represents another celestial body within the solar system, or a node, in addition to representing metaphysical concepts of good fortune, and the characteristics and personalities of religious figures. For traditional purposes and the purported health benefits, the arrangement of the stones and their position to the body is of particular significance, as is the quality of the gemstones.
