National Collect Rocks Day

National Collect Rocks Day is dedicated to collecting rocks. This fascinating hobby allows many people at the same time to study the natural origin of the stone, its structural features, and the time it appeared on the planet. It is celebrated on September 16th.


The collection of stones appeared thanks to the science of geology, which arose in the 19th century. Many researchers began to wonder how and when the planet formed. Rocks are an excellent object for analysis and research. Their age is hundreds of thousands of years and can tell us about the features of the formation of the Earth.

The first geologist is considered to be James Hutton, who at an advanced age decided to devote himself to the study of rocks. He destroyed many of the theories that existed before; for example, that all rocks could only form under water.

By the beginning of the 20th century, the approximate age of the Earth was already known. A theory about the formation of continents was put forward, and so on. Many people began to collect rare stones and rocks. For some, this is just a hobby with the opportunity to make good money (some stones are very rare and valuable), while for others, this is a real immersion in the history of their planet.

Interesting facts
