Pink Chalcedony Limb Cast Cabochon - Nevada

Solid pink chalcedony limb cast from Texas Springs, Nevada. These are hard to come by, and even harder to find without fractures.

Limb cast is a type of fossil formed when a tree branch decomposes and leaves a cavity, which is then filled with minerals, typically chalcedony, agate, or opal. This process essentially creates a stone replica of the original branch, preserving its external shape and features like bark texture and branch form, but not the internal wood structure.
