Blue Agate sphere with crystallized heart.
PUMI1769-1
This blue Agate sphere from Brazil has been of course polished. But at the beginning it was indeed a blue Agate geode that was practically round, and by polishing it, this opening with a shape of "Pacman’s mouth" appeared, making visible a fully crystallized heart. These crystals are hematoid, and this tint is related to the oxidation of the iron ore contained in the water that infiltrated this geode several million years ago.
