Kentucky Agate Cut Geode Nodule - Yellow, Gray, Gold-ish, Tan Colors - KYA5

Fantastic yellow, gold-ish, gray, white and tan colored sliced geode nodule section of rare central Kentucky agate! Backside shows the outer rind of the agate geode nodule.

Kentucky agates are rare in that they form in sedementary rock. They appear to be originally crinoid heads, brachipods and other fossils in the limestone that had been expanded by evaporate minerals. The evaporate minerals were dissolved leaving behind the voids for any minerals such as chalcedony to fill in later. Most central Kentucky agates display fractures on the inner agate from how they formed and geologic changes to the area over time. Typical colors are yellow, black, white and bluish-gray while the agates with brighter colors like red, pink purple, green show up from time to time. The black and red color combo is considered a desirable and is the most expensive.

This piece shows some small fractures but is solid overall. This piece is cut but not polished. Great specimen for any collector or a lapidarist.
