This is a pale cream to white calcite cluster characterised by several upright, column-like projections rising from a broader base. The surface is drusy and rugged with an irregular, jagged outline and scattered tan to brown surface staining. The piece measures 11 × 11 × 6 cm and weighs 318 g. The cluster shows a range of columnar projection sizes across the base, with drusy crystal surfaces visible on most faces and occasional staining on exposed areas.
