Individuals who look for gems and valuable metals are often called prospectors or gemologists. They typically search in areas known for mineral deposits, such as riverbeds, mountains, and mines. Popular locations for finding gems include regions like the Appalachian Mountains in the U.S. for garnets and sapphires, and parts of Africa and South America for diamonds and gold. Additionally, many hobbyists scour public lands and gem shows for opportunities to find and purchase valuable stones.
