The image shows a piece of black and white crystals on a white surface, which is believed to be a combination of pyrite and calcite. The crystals are arranged in a symmetrical pattern, with the black crystals in the center and the white crystals radiating outward. The pyrites are a deep black color, while the calcite is a lighter shade of white. The contrast between the two colors creates a striking visual effect.
