Agate slice on black base: ring of fire!
PUMI1871-9
Natural black agate from Brazil. In any case, very dark, and we can guess nodules inside. However, as it is cut into thin slices, it becomes translucent and lets the light pass through on photos 3 and 4. And it is completely transformed by a real ring of fire! Sauron’s eye? Each his references...
