This lot comprises a collection of geological specimens identified by accompanying labels as Liesegang Weather Rock. The group includes several cut and partially polished rectangular blocks of varying sizes, one irregular slab, and one large stylised carved figure, possibly representing an aquatic creature or bird, which displays vertical banding. These specimens are composed of chemically weathered siltstone, exhibiting prominent Liesegang banding caused by the rhythmic precipitation of iron minerals. The included descriptive labels state that the dark rings are iron-enriched and the light rings are iron-depleted, while the white areas consist of kaolin and silica. The specimens feature a palette of earthy tones including tan, brown, and cream. Small printed labels bearing the text A & R Fine Art are associated with the lot.
Condition report:
The specimens are in good stable condition. Several pieces have been cut or partially polished to reveal internal geological patterns. Natural surface textures, minor edge wear, and light surface abrasions are present, consistent with the material and handling.
