Coral

Coral has been called the "garden of the sea" because it was once believed to be a plant. Instead, coral belongs to a small, but important group of organic gemstones. Coral is formed through a biological process rather than being a mineral with a crystalline structure like most colored stones. Coral jewelry has been found in ancient Egyptian and prehistoric European burials and was especially popular during the Victorian age. It is a symbol of modesty, wisdom, happiness and immortality.
