The image shows three artifacts displayed in a glass case. On the left side, there is a black knife with a curved blade and a pointed tip. Next to it is a rectangular piece of stone with a rough texture and a small hole in the center. The stone appears to be old and weathered, with some cracks and chips visible on its surface. In the middle, there are two smaller pieces of stone, one with a smooth surface and the other with a slightly rough texture. The other two pieces are also made of stone and have a similar shape and texture. All three artifacts are displayed on a beige background.
