The image shows four different types of rocks displayed on a white surface. On the left, there is a large, dark-colored rock with a rough, uneven surface. Next to it, there are two smaller rocks, one black and one gray, with a slightly rough texture. In the middle, there appears to be a small, rectangular stone with a pointed tip. The third rock on the right is slightly larger and has a smooth, polished surface. All four rocks appear to be old and weathered, with visible signs of wear and tear. The numbers "7", "8", and "9" are visible on the bottom right corner of the image.
