The image shows two small rocks on a white surface. The rocks appear to be made of a dark material, possibly stone or rock, and are of different sizes and shapes. On the left side of the image, there is a small, rectangular rock with a rough, uneven surface. It is black in color and has a rough texture. The rock on the right side is larger and appears to be slightly larger than the one on the left. There is a maroon-colored label on the bottom right corner of the display case with Chinese text written on it. The text on the label is written in both English and Chinese characters.
