Mineral Specimen (possibly gold ore or pyrite-bearing quartz)

This item is a rough, unworked mineral specimen, likely a rock containing various mineral deposits. It is irregularly shaped, consistent with a naturally occurring fragment broken from a larger rock formation. The dominant colors are earthy tones, primarily a rich yellowish-brown to golden-yellow, interspersed with darker grey, black, and possibly some lighter grey or whitish areas. The surface appears uneven and crystalline in parts, displaying a rugged texture with visible cleavages and fracture planes characteristic of natural rock. There are distinct patches of what appears to be a metallic, possibly sparkling or reflective, yellowish material, strongly suggesting the presence of either gold or a sulfide mineral like pyrite (often referred to as 'fool's gold'). The grey and black areas might indicate the presence of other base metals, quartz, or host rock. One edge shows a somewhat clearer or more translucent mineral, potentially quartz. While no specific size measurements can be definitively determined from the image, the item is held between a thumb and forefinger, suggesting it is relatively small, perhaps a few inches in its longest dimension. There are no discernible markings, signatures, or manufacturing details, as it is a natural specimen. The overall condition is as-found, with no obvious signs of recent damage or repair; its ruggedness is inherent to its natural state. Its estimated age would be geological, formed over millions of years. This specimen's main appeal lies in its potential mineral content and raw, natural beauty.
