Florida Agatized Coral

$5.00Price

Coral is the outside skeleton of tiny ocean animals called polyps, they had lived in colonies attached to hard underwater surfaces. When they were alive, polyps combined their own carbon dioxide with the lime in warm seawater to form a limestone-like hard surface, or 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 takes 20-30 million years for agatized 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 for Florida and is found in three main Florida locations: Tampa Bay, the Econfina River, and the Withlacoochee/Suwannee river beds.
