Chalcedony-replaced Coral geode

Item Description

A sculptural, very showy pair from a sliced and polished hollow, very elongate colony of coral - you can see the pattern on the outside - that has been replaced or filled inside with botryoidal and banded chalcedony. The lustrous, translucent botryoids and banding have a pleasing variety of honey-brown color! This is one of those unusual cases where biology meets mineralogy. This dramatic specimen is a fine pair from this old locale.
