| One case has a selection of crystal-lined geodes, several filled with amethyst, from the Josini area of northern KwazuluNatal in South Africa. |
| The designs on the lower part of the structure are somewhat formal, but the upper part is a free-form mix of geodes, dripstone, and what appear to be inverted stalactites. |
| Some visitors gather around the sparkling amethyst geodes or the shining pyrite crystals. |
| Mordenite lines most of the geodes as the typical fine hairlike crystals of the species. |
| Two adjacent geodes from the same piece of shale could be cracked open, and one would be lined with brown calcite, the other with quartz. |
| Most of the thirty-two pages on Moroccan agate are color plates of superb geodes with fantastic patterns and inclusions. |
