It is connected with planet Mars. The metal with which it associates is gold/copper. It rules over ear, nose, gall bladder, uterous, rectum and red bone marrow. It can be worn by those whose ascendant is Cancer, Leo,scorpio,sagittarus and Pisces. It should be worn in ring finger.
Coral is made of deposits of calcium and secretions from the invertebrate "coral polyp". The deposits are built up in a structure resembling plants with branches. This creature generally lives in calm water and builds the corals in depths from 20 feet to as deep as 1000 feet. Red corals are this color due to iron oxide within them and are generally found in depths of 100 to 150 feet. The shallower the water the darker the color of coral and, obviously, the deeper the water the lighter the shades of color found.
To strengthen Mars, wearing a red coral stone (best), or strand of beads is recommended. The deeper red it is in color the more potency it will have. I have seen startling results from proper use of this gem, even in the area of sexual desire and performance in men. Unfortunately this gem was becoming in short supply due to uncontrolled farming of our seas. It is now illegal to take coral from the sea, so all that is on the market is from previous stocks and the finest qualities are considered very rare.
The wearing of this stone will increase vitality, courage and ability to work on endeavors through to their fruition. Physically it is said to strengthen the immune system, the muscles of the body and the male reproductive system.
The main sources of red coral were the Mediterranean, Persian Gulf, Red Sea, Africa, Australia, Taiwan and Italy. We have also been receiving some red corals from Tibet, which suggests that at one time the sea came up to this mountainous country. Red jasper may be used as a substitute for red coral, having similar properties but in a lesser degree.
