Fossil coral is a natural gemstone formed from ancient coral remains. When prehistoric corals are fossilized through replacement with agate, a variety of naturally occurring chalcedony or microcrystalline quartz, the fossil quartz forms through hardened deposits left by silica-rich waters. These gemstones often have a flower-like pattern from the coral skeletons and occur in a wide range of colors from chalky whites to pinks, to browns, grays, blacks, yellows and reds. AKA - Agatized Coral, Agatized Fossil Coral.
