caption: The image shows a piece of malachite, a type of green mineral, on a gray background. The text at the top of the image reads "malachite tsumeb, namibia". The malachites have a glossy, emerald-green hue and are arranged in a symmetrical pattern, with some of them overlapping each other. The surface of the mineral is smooth and glossy, reflecting the light and creating a beautiful contrast between the two colors.
