caption: The image shows a piece of rock with a number of crystals on it, and at the top of the image there is some text. The rock appears to be a pallasite, a type of crystalline mineral composed of small, irregularly shaped crystals. The crystals are arranged in a symmetrical pattern, with some of them overlapping each other. The colors of the crystals range from light brown to dark brown, and the texture of the rock is rough and bumpy.
