The transformation of coral into agatized coral begins when coral polyps die, leaving behind their hard, calcium carbonate-based skeletons. The coral skeletons become buried in sediment, which helps to protect them from degradation. Over time, minerals such as agate, calcite, or silicate replace the calcium carbonate that composes the coral's structure. This replacement not only preserves the intricate details of the ancient coral but also gives the resulting stone a distinctive banded appearance, known as agatized coral.
In Tampa, Florida, agatized coral, designated as the state stone, offers a glimpse into the distant past, dating back approximately 38 to 25 million years during the Oligocene-Miocene period. These fossils, primarily of the Montastrea species, are discovered in ancient seabeds where silica-rich groundwater has flowed through, methodically replacing the original calcium with silica and leaving behind ornately patterned fossils. The array of colors in these agatized corals, including shades of white, gray, brown, black, yellow, and red, comes from different trace minerals within the agate. This variety adds to their allure, making them highly coveted by collectors. Found in locations such as the Tampa Bay area near Ballast Point and further north along the Withlacoochee River in Madison County, these fossils are scientifically significant and aesthetically pleasing, capturing the attention of enthusiasts and researchers alike.
This listing is for one crystal, as pictured. Please see all photos and videos, and feel free to message me with any questions. I take pictures in lighting that best represents the crystal, but monitor settings may slightly affect the colors displayed on your screen.
All crystals have been carefully hand-selected for their quality and aesthetic appeal, ensuring you receive a beautiful piece.
