Fool’s gold is made up of crystals and has sharp edges, while real gold is a metal with a smoother texture and rounder edges. If you look closely at the piece and see that its structure consists of what looks like small and sharp cubes, then it is fool’s gold.

Where is gold most commonly found?

About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons). Most of that gold has come from just three countries: China, Australia, and South Africa. The United States ranked fourth in gold production in 2016.
