Agatized Fossil Tabulate Coral (Polished)
Indonesia
Miocene age (approx 20 million year old)
Data: This interesting natural color stone was formed from ancient coral beds in Indonesia. Over the course of a very long time - perhaps 20 Million Years - the coral skeletal remains were gradually replaced with agate, chalcedony, or microcrystalline quartz, in a cell by cell replacement process that leaves flower-like patterns from the fossil skeletons imprinted three dimensionally in the stone.
