পর্ব 2: রুরির সোনার সম্ভাবনা এবং নগদ মূল্য ও বৈজ্ঞানিক মূল্যের পার্থক্য আবিষ্কার

Nagi takes Ruri to a gold prospecting district. Gripped by gold fever, Ruri gains skill with her new rock hammer. But the stones she splits contain only pyrite, confirmed by streak test. A crystal with an unexpected shape prompts a discussion about the difference between cash value and scientific value. Next they pan for placer gold in a stream bed, finding better success after a heavy rain. Searching a pothole yields even more gold, including a huge nugget that Ruri would rather keep than sell.
