The image shows a rock with a small amount of calcite on top of it, resting on a surface with some text written on it. The calcite is a light gray color and has a rough texture. It is small and round, with a few small bumps and ridges along its surface. The text on the rock is written in a bold font and is likely a description of the calcite.
