SPECTACULAR LARGE
"MOUNT EVEREST" AGATIZED CORAL GEODE WITH
DRUSY CRYSTALS "SNOW PEAK" AND BOTRYOIDAL CRYSTAL
"CAVE"
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.
The specimen being offered here is
one-of-a-million compared to what is usually discovered! It is
probably one of the most visually intriguing we have offered of many
amazing specimens in our inventory. The entire piece looks like a
steep snow-capped mountain with a fascinating cave inside. There
is a "peak" of snow white drusy crystals on the top tip. The inner
chamber is hollow and goes all the way through the geode. This
cavity is completely lined with BOTRYOIDAL structures which have
an eerie translucent appearance. Of all
the typical agatized
coral examples found ANYWHERE in the world, RARELY will you ever
encounter agatized coral with stunning crystal structures as seen
here. 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.
Highly visually appealing and certainly can be considered the finest of
the finest! Unusually large and entire sawn face is polished to
perfection revealing the layers of chalcedony as it formed.
Absolutely
NO ENHANCEMENT, NO DYEING, NO REPAIR and NO
RESTORATION.
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.
