PHOTO ABOVE SHOWS BACK SIDE WITH MORE EXPOSED FOSSILIZED CHAMBERS BUT WITHOUT THE DRUSY

RARE GEM GRADE RED DRUSY BOTRYOIDAL MICRO-CRYSTAL LINED AGATIZED FOSSIL CORAL GEODE

WITH BIZARRE SUSPENDED INTERNAL STRUCTURE

Withlacoochee River - Florida, USA

OLIGOCENE PERIOD :  38 million years ago

Agatized fossil coral is highly prized by not only fossil collectors, but by gem and mineral collectors, as well.  Exquisite forms from Florida are especially in demand as the state produces some of the finest examples of this geological oddity in the entire world.  The majority of agatized coral that is collected is either solid inside when sliced or it possesses a drab and rather uninteresting structure to its internal cavity.  This remarkable specimen is VERY rare and far exceeds the beauty, color and internal crystalline structures of most agatized coral pieces that are found. 

This is THE SECOND of two pieces we ever acquired that has a RED drusy microcrystal agatized chamber.  This piece had been in the private collection of the original owner and then in our private collection since we acquired it.  It is the best last specimen we have to sell and in the most rare of all the colors of these ever found WITH DRUSY crystals.  The inner cavity of the colony is covered with rod-shaped and bubble-shaped botryoidal structures which once were the former polyp channels of the coral creatures.  There is an additional rare feature of this piece - a floating and suspended portion of the colony that fossilized and can be seen attached from the top of the geode ceiling.  This part has fossilized from a plum red base to a bright tomato red surface of the majority of the structure.  The entire lining of the geode varies from blood red, hot orange and plum red and then transitions to one side of the base wall into white!  The "floor" is lined with bright orange red structures.  Making this an ultra-rare gem beauty is the fact that UNLIKE THE MAJORITY of fossil coral geodes, this specimen is COMPLETELY LINED INSIDE WITH TINY DRUSY MICRO-CRYSTALS that have taken all the colors of the walls. 

The specimen being offered here is one-of-a-million compared to what is usually discovered!  This stunning example is a part of a hollow fossil geode that was once a prehistoric coral colony.  The internal cavity displays the RAREST of all crystal structure types in these fossil corals - heavy drusy-coated crystal structures.  The cavity is completely lined with glistening RED drusy crystals OVER BOTRYOIDAL structures which have such an intense sparkle that the inside appears to be coated in cinnamon red-colored diamonds.  From our private museum collection and last of two available for sale.

Of all the typical agatized coral examples found ANYWHERE in the world, RARELY will you ever encounter agatized coral with stunning drusy crystal structures over botryoidal structures in white like this.  Agatized coral of this quality is so rare that usually it is cut up and used in very expensive custom jewelry pieces.  As a complete crystal specimen, it is worth even more in its natural state.  Absolutely NO ENHANCEMENT, NO DYEING, NO REPAIR and NO RESTORATION.  One of the rarest of the rarest we have ever offered!

Agate, also known as chalcedony, is a type of cryptocrystalline quartz (SiO2).  Under unique geological conditions, prehistoric corals and mollusks can fossilize by being replaced with agate from silica-rich ground water percolating through limestone.   The Florida Legislature designated agatized coral as the Florida State Stone in 1979.  The statute describes it as “a chalcedony pseudomorph after coral, appearing as limestone geodes lined with botryoidal agate or quartz crystals and drusy quartz fingers, indigenous to Florida."  Agatized coral occurs in a variety of colors, typically gray, brown, black, yellow, white, and on rare occasion red.  The majority of Florida’s agatized coral formed in Oligocene-Miocene Hawthorn Group sediments.  Fossil agatized coral is occasionally dredged up in the Tampa and Clearwater areas but also occurs in limestones along the Econfina, Withlachoochee and Suwannee Rivers.

Fossil corals were simple marine invertebrates that possessed a sac-like body called a polyp with a mouth and tentacles.  As carnivores, they would immobilize or kill their prey with their stinging tentacles then swallow their prey and later expel the wastes through the same mouth.  They formed a dense outer skeleton of calcium carbonate which, when living in large colonies of thousands of cloned individuals, formed a massive structure.  The complex folds in their stomach cavity can be seen in the wondrous detail left behind in their skeletons.  Modern corals today share a symbiotic relationship with algae that covers their body tissue.  The algae supplement the coral with oxygen which most likely was the case in prehistoric times, as well.

Prehistoric corals are believed to have thrived in the same environments that modern corals prefer - clean, warm oceans of normal salinity levels.  Solitary corals were present in oceans of soft, muddy bottoms while horn corals and colonial corals preferred hard sea floors to attach themselves.
