The image shows a display case with a blue velvet background. On the display case, there are nine small white cards arranged in a grid-like pattern. Each card has a small image of a rock or stone on it. The rocks appear to be of different sizes and shapes, with some having a rough texture and others having a smooth surface. There is also a small white card with Chinese characters on it, which likely contains information about the rocks. The display case appears to be in a museum or exhibition space.
