The stone of these banded agate geode bookends have been enhanced with blue to show off the detailed textures of the geodes. They were originally plain white to clear gray.
The enhancement is done soaking the geode in chemicals (such as iron sulfate, prussiate of potassium or potassium ferrocyanide) for long periods of time.
