Bought a 'rare' thunder egg online and it was just a painted river rock
Spent $75 on what the seller said was a top grade Oregon thunder egg. It arrived looking way too perfect, like a shiny brown egg. I took it to the local rock club meeting and one guy just laughed and said it was a smooth stone from a craft store with spray paint on it. I tried to scratch it with a steel nail and the color came right off. Anyone know a good way to spot fakes before you buy?
