The image shows a display case with four different types of rocks on it. The rocks are arranged in a row and are of different sizes and shapes. On the left side of the display case, there is a large rock with a rough, uneven surface and a pointed tip. The rock appears to be made of a light-colored material, possibly stone or mineral, and has a rough texture. Next to it, there are two smaller rocks, one with a darker color and the other with a lighter color. The larger rock on the left is slightly larger than the other two, and it has a smooth, polished surface. The smaller rock in the middle is smaller and has an irregular shape, while the smaller one on the right is larger and more rounded. All four rocks have a red label with Japanese text on it, which likely provides information about the rocks.
