This is an incredible septarian geode from Mexico that was hand carved into a sphere. The cavern of calcite crystals goes all the way through the sphere and has a few small formations of barite within. The calcite crystals are UV reactive and glow a greenish/yellow under a long-wave UV flashlight!

Septarians are the result of volcanic eruptions and formed about 50 million years ago. Organic matter from the sea chemically bonded to the sediment around these volcanic eruptions and formed balls of mud. When the oceans receded, the decaying organic matter seeped into the cracks in the balls of mud and began forming Calcite crystals. A layer of Aragonite formed between the inner calcite and the outer gray Limestone.
