The image shows three pieces of rock displayed in a glass case. The rock appears to be old and weathered, with a dark brown color and a rough texture. The pieces are arranged in a triangular formation, with the largest rock in the center and two smaller pieces on either side. The largest rock is slightly larger than the two smaller ones on the left and is slightly smaller than the one on the right. All three pieces have a rough, uneven surface and appear to be of different sizes and shapes. The glass case is transparent, allowing the viewer to see the rocks inside.
