We Collected These Agatized Coral Specimens In The 1970's In Florida.
The sites, where we collected these specimens, are no longer available to collectors. Agatized coral is scientifically identified as Chalcedony Pseudomorph after Coral. Agatized coral occurs when silica in the ocean water hardens, replacing the limy corals with a form of quartz known as chalcedony. This long process (20-30 million years) results in the formation of a "pseudomorph," meaning that one mineral has replaced another without having lost its original form. In 1979 agatized coral was designated the official state stone of Florida.
