Collection of Assorted Geologic Rocks and River Stones

This is a diverse assembly of eight individual mineral and rock specimens, varying significantly in geological composition, size, and texture. The largest specimen is a light-colored, angular sedimentary or metamorphic rock, roughly 6-8 inches in length, exhibiting a tan-to-cream palette with visible pitting, surface crystallization, and iron-staining oxodization. The collection also includes several water-worn river stones; one is a smooth, tan oblong pebble, while another is a flat, grey, rounded stone showing glacial or fluvial weathering. A distinctive dark grey specimen at the top displays a grainy igneous texture, potentially basalt or gabbro, with a speckled crystalline surface. A smaller, reddish-brown stone appears to be hematite-rich or clay-based with a jagged, irregular fracture pattern. One small specimen features interesting white inclusions or possible small fossilized imprints on a dark matrix. The condition across the set is natural and unpolished, showing raw geological features such as surface dust, minor fractures, and varied levels of lithic weathering. There are no signs of lapidary work or artificial shaping. The items are shown on a splattered industrial workbench, suggesting they are field-collected specimens rather than retail-prepared decorative stones.
