This Calcite Crystal sphere has a very desirable golden color with great definition and an outstanding pattern. The Septarians were formed during the Cretaceous period, 50 to 70 million years ago when the Gulf of Mexico reached what is now Southern Utah.
Decomposing sea life killed by volcanic eruptions were chemically attracted to the sediment around them and formed mud balls. As the ocean receded, the balls were left to dry and crack, trapping decomposed calcite from the shells and crystals formed. A thin wall of calcite was transformed into aragonite separating the bentonite heavy clay exteriors from the calcite centers.
Because of this phenomenon, the nodules are called septarians. The name Septarian is derived from the Latin name, Septem, meaning seven. The fact is that the mud balls cracked with 7 points in every direction, thereby creating this beautiful design. Septarians are composed of Calcite (The Yellow Centers), Aragonite (The Brown Lines) and the Outer Grey Rock is Limestone. Occasionally the fossil or some of the fossils which started the formation of the rock is noticeable in the rock.
Would be a beautiful addition to any new or existing collection.
