Banded Chert or Slate Rock Fragment

This item is a small, hand-held mineral specimen, likely a fragment of banded chert or perhaps a water-worn piece of metamorphic slate. It measures approximately 2.5 to 3 centimeters in diameter across its widest points. The rock exhibits a dark charcoal-to-black base color with distinct, parallel light gray or off-white strata or banding running across one primary face. These bands suggest a sedimentary origin with subsequent mineralization or pressure-related metamorphic changes. The shape is roughly rhomboidal or sub-angular, with edges that appear somewhat smoothed by natural erosion or alluvial action, though some sharper fracture points remain visible. The surface texture appears matte rather than glossy, showing a natural dull luster typical of fine-grained siliceous rocks. There are no signs of artificial working, carving, or tool marks, indicating this is a natural geologic occurance rather than a man-made artifact or 'lithic' tool. The condition is raw and natural, with minor pockmarks and surface variations consistent with field-collected mineral samples. No maker's marks or signatures are present as the item is a specimen of nature. Estimated age is geologic, potentially dating back millions of years depending on the stratigraphic layer of origin.
