caption: The image shows a piece of rock with a black and white pattern on it, resting on a white surface. At the top and bottom of the image, there is text that reads "Muscovite with Ankerite". The rock is composed of a variety of shapes and sizes of stones, with some of them having a glossy finish and others having a matte finish. The stones are arranged in a symmetrical pattern, with the largest stone in the center and the smallest stones radiating outward. The colors of the stones range from black to white, creating a unique and eye-catching contrast.
