The exact origins of National Collect Rocks Day are unclear, but rock collecting has been popular for centuries. People have long gathered unusual stones, crystals, fossils, and minerals for study, decoration, trade, and personal enjoyment.

The hobby became closely connected with the development of geology, especially during the 18th and 19th centuries. Scientists such as James Hutton helped shape modern ideas about Earth’s age, rock formation, and natural processes.
