RARE >5 LB SEPTARIAN HEART GEODE W/ FOSSIL CRAB , A +++ QUALITY & FLUORESCENT!

Description

This is a very rare and very fine example of a septarian geode that has shaped into a heart with a beautifully preserved  fossil crab ! The fossil crab sits within its own little geode cavity. In fact ,it sits loosely within the cavity and can be removed. The miner who shaped the specimen into a heart has placed a piece of tape over it so the crab doesn' t come ajar and get lost. The specimen is under no uncertain terms TOP QUALITY!
As can be seen in the last two photos it is also beautifully fluorescent under UV light! The last photo reveals the phosphorescence upon withdrawal of the short wave UV lamp.
This is a great specimen to add to the collection of THE most finicky collector.
This specimen has it all... superb quality daylight specimen, rare fossil and fluorescent!!!!
Delicate in grain and texture , these distinctive decorator specimens are found in Utah 20-40 feet below the earth's surface. Septarians were formed 50- 70 million years ago when The Gulf of Mexico extended up to what is now the Central United States.
Decomposing shell and sea life on the ocean floor had a chemical attraction for the sediment around them, forming concretions. As the oceans receded, the rolling action of the waves resulted in the formation of nodules, that were eventually  buried in the mud. As the balls dried and cracked , mineralized solutions ,carried by ground water, were deposited into the cracks forming brown aragonite and golden yellow calcite. The gray mineral is fossilized mud or limestone . Solid septarians are most common. They are most often cut into slabs , or if the specimen is just right, polished into beautiful free forms, shaped into hearts or made into bookends. About 20- 30% of the nodules are hollow or are geodes. Rarely included calcite or barite are found in the specimens. Fossils can also be embedded in the gray limestone.
The name septarian is derived from the Latin name Septem, meaning seven . This relates to the fact that the mud balls cracked with seven points in every direction. Also, the yellow calcite, is separated from the gray fossil mud by a rim of brown aragonite.
Septarians are said to bring calming energy and feelings of joy. They are spiritually uplifting and nurture communication. They are purported to help with healing of the kidneys and blood disorders.
As far as septarians go this is a true unique OUTSTANDING QUALITY specimen & fossil !!! It is terriffic under UV light and certainly as a "daylight" specimen!
For fluorescent mineral enthusiasts: the specimen  fluoresces under short ( photo 12 ) and long wave ( photo 11 ). The calcite  also retains a nice phosphorescence when the short wave light is removed (Please see photo 12) !  Short wave photos taken with Super Bright Lamp, long wave with 36 watt Way Too Cool Lamp. Please note any blue color is reflected UV light.
Please note special UV lights are mandatory to visualize the fluorescence!
