The image shows three small rocks on a white surface. The rocks are arranged in a triangular formation, with the largest rock in the center and two smaller rocks on either side. All three rocks appear to be made of a light-colored material, possibly stone or rock, and have a rough, uneven texture. The largest rock on the left is slightly larger than the two smaller ones on the right. The background is plain white, and there is a label at the bottom of the image that reads "13".
