Fossil coral is a natural stone that is formed when ancient coral is gradually replaced with agate. The actual name is agatized coral or agatized fossil coral. 
Fossil coral can exhibit a wide range of natural colors, and may vary widely within a single stone depending on weathering, oxidation and the original mineral content. The fossilized coral typically appears as small flower-like patterns in the stone.
Of the varieties of fossilized corals found throughout the world exquisitely detailed specimens from the mountains of Indonesia are among the most unique. Florida and Georgia in the USA are also import sources of fossil coral. In fact Florida has declared fossil coral to be the Florida State Rock.
