Coral is one of the organic gem materials, consisting of the calcified skeletons of coral polyps. These polyps are tiny, primitive organisms that eventually attach themselves to previous coral growth and secrete substances that are similar to calcite. The chemical composition of coral is calcium carbonate with magnesium carbonate and traces of organic substances. In gem trade red, pink and white corals are the most favored colors. Coral is sensitive to heat, acids and hot solutions and the color can fade when worn during long run. White coral can strengthen your self-esteem and help to clear frustration and resentment and it also helps to take sound judgment and provides recognition.
