Technical Details
Description
The agatized or silicized coral is composed of silice, fundamental element in the process of fossilization of what was originally a coral.
The original structure of calcium carbonate of the coral was replaced by silica in cryptocrystalline form (agata) by a slow path, the pseudomorphism, that allowed to keep pthe original structure of the coral.
