Group of Four Natural and Dyed Quartz Geodes

A collection of four quartz geodes, including one with a vibrant pink dyed exterior and interior, one with a greyish-blue chalcedony center, and two natural clear to white crystalline quartz specimens. The geodes vary in shape and size, showing natural rocky exteriors and sparkling crystalline interiors. One specimen appears to be a solid nodule rather than a hollow geode.
