The image shows three pieces of mineral specimens displayed on a wooden surface. The specimens are arranged in a triangular formation, with the largest piece in the center and two smaller pieces on either side. The largest piece is a large, irregularly shaped rock with a rough, crystalline surface. It has a dark blue-grey color and appears to be a type of mineral, possibly quartz or fluorite. The smaller piece on the left is smaller and has a smooth, polished surface, while the larger one on the right is larger and more crystalline-like. All three specimens have small white labels attached to them with Chinese characters.
