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 beautifulfree 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 arepurported to help with healing of the kidneysand blood disorders.

As far as septarians go this is a trueunique OUTSTANDING QUALITY specimen!!!

For fluorescent mineral enthusiasts: the specimen fluoresces under short ( photos 6-9) and long wave ( photos 1,-5. The calcite also retains a bright phosphorescence when the short wave light is removed( photo 9). 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.

The specimen contains both clear and yellow calcite. This is much less common with these specimens.

Please note the \"wavy\" texture to the calcite that is evident when held to light!

Last two photos show back of specimen. The small elliptical section near the middle of the specimen may be a section of fossil crab.

Please note special UV lights are mandatory to visualize the fluorescence!
