The image shows three pieces of stone displayed on a white wall. The first piece on the left is a rectangular shape with a flat top and a slightly curved bottom. It appears to be made of a light-colored material, possibly stone or a similar material. The second piece in the middle is a larger, more elongated piece with a rough, uneven surface. It has a small indentation in the center, possibly indicating that it has been exposed to the elements for some time. The third piece is slightly smaller and has a more rounded shape. All three pieces are arranged in a triangular formation, with the largest piece at the bottom and the smallest at the top. The number "12" is visible in the bottom right corner of the image.
