Approximately 20 million years ago, volcanic activity buried the coral reefs located in Indonesia. The ash provided the Silica for the Agate replacement of the original skeletal structure of the ancient coral. Each coral specimen is unique and different. The ash contained Manganese and Iron, which aided in the development of the different color patterns. Fossil coral is usually distinguished from other corals because it has a waxy luster and a floral pattern. Unlike other coral specimens, the ancient Agatized coral is more dense and this is due primarily to the silica content present. Coral has been prized as a gem because it was believed to hold sacred and powerful properties. Ancient Egyptians would place a piece of coral in the tombs of the deceased to ward off evil spirits. The Romans would hang branches of coral around the necks of their children to protect them from danger. Whether you are seeking a good luck charm for the new year or love to collect minerals and fossils, this ancient treasure has the best of both.
