This kind of fossil coral is a natural stone that is formed when ancient coral, over long periods of time, is gradually replaced with Chalcedony/Agate. Agatized coral typically appears as small flower-like patterns in the stone and can form in a wide range of natural colors. These specimens were found in tertiary sediments. The coral was smothered in volcanic ash 10 million years ago, leaving the cavities which then filled with the Agate/Chalcedony.
I adore this Agatized Coral specimen. The brown banded color is smooth and glossy and within it is the botryoidal appearance of the bubbly coral. This fossilized coral is ideal for any collector who is interested in unique specimens.
