HOW TO Tell the Difference Between Real Gold and Fool''s
Without zooming in, it can be tough to tell the difference, especially when the sun is shining and the water makes everything glisten. Here''s a closeup of iron pyrite (fool''s gold) and actual gold side by side. One of the major differences between the two is that pyrite has hard edges, gold has softer edges.
