Fossil coral is a natural type of gemstone formed by ancient corals. Corals are made up of small invertebrate animals, known as zooids, that look like tiny sea anemones. They feed on small food particles they find in the water around them. The proper name for fossil coral is ‘agatized coral’ or ‘agatized fossil coral’, because, during formation, the coral remains are gradually replaced with agate, a variety of naturally occurring chalcedony, or microcrystalline quartz. When prehistoric corals are fossilized through replacement with agate, the fossil coral forms through hardened deposits left by silica-rich waters.
