Hello, Jordin, I am sorry for my late response to your submission.
Geological sedimentary rock formation
This chert nodule likely originates from ancient sedimentary rocks, where silica has slowly accumulated and hardened over time. It may have formed through the replacement of calcium carbonate during the formation of rock from sediment.
This nodule exhibits a unique shape and natural texture, making it a compelling conversational piece. Its surface may display a weathered cortex surrounding a second interior of a different composition. While generally opaque, some areas may exhibit slight translucency or glint from small mineralization crystals.
A defining characteristic of chert is its extreme hardness, ranking 7-8 on the Mohs scale. This nodule exhibits the conchoidal (shell-like) fracture, a property that allows it to break with smooth, curved surfaces and razor-sharp edges. This feature was essential for early tool-making all across the globe.
While this rock formation is fairly common; Its unique shape, color variations, make it a great addition to any rock or mineral collection.
