Agate / Crystal Geode

Dark banded rings surround a pale, bumpy heart in each half.

This is an agate and crystal geode. A geode is a hollow rock lined with mineral crystals, and it forms when mineral-bearing water slowly deposits material inside a cavity over a very long time. Paired round halves with a thin speckled white shell and a wide band of brown-black with blue-grey fading inward. At the center, a white cavity holds a pale lumpy cluster. The surfaces are polished and smooth. It is 4 inches wide, 4.5 deep and 3.5 high.

Like a pair of very patient eyes.
