Item details

This Septarian geode (or nodule) cabochon was custom hand-cut for me by a Russian lapidary artist. Septarian Concretion or Septarians nodule were formed during the Cretaceous Period, around 50 to 70 million years ago.
Sea levels were much higher then and the Gulf of Mexico reached inland to Southern Utah where many of the septarian nodules are found. They are also found in Madagascar where conditions were similar. Periodic volcanic eruptions killed the smaller sea life which sank to the sea bed and started decomposing. The minerals in the shells and carcasses attracted sea floor sediments which accumulated around the carcasses and formed nodules or mud balls. When the ocean eventually receded, the mud balls dried out and began to shrink and crack into the beautiful patterns that you see inside the septarian nodules.

Septarian is a geode that is a combination of yellow calcite, brown aragonite, grey limestone and white/clear barite, thus it has properties of each of its component minerals.
Color: Yellow, brown, white, clear

Here, in my shop, I am proudly offering a great collection of these unique fossils cut into gorgeous cabochons. Most of them are large scale cabs. They have unique shapes being completely flat on top and having beveled sides. They all cut professionally with highly skilled artist and have a nice polish on both sides. You will not find these stones anywhere else, but in my shop.

This cabochon measures 54mm x 6mm (width)

Enjoy crafting! <3
