Natural Fossil Coral Cabochon

Fossil coral, also known as petrified coral, is a type of ancient coral that has been transformed into stone through a process of mineralization. It is formed when living coral colonies die and become buried in sediment, which over time is replaced by minerals such as quartz or calcite. Fossil coral can be found in a variety of colors and patterns, and is often used in jewelry and decorative objects due to its unique beauty and historical significance. It is also studied by scientists to gain insights into the earth's past climate and ecology.
