Understanding Coral Rock
Coral rock is primarily derived from the skeletal remains of marine coral, which are produced by small marine invertebrates known as polyps. These creatures build their colonies over thousands of years, which eventually form coral reefs. When coral polyps die, their hard skeletons accumulate, leading to fossilization and the creation of coral stones and gems.
