How to Differentiate Between Gold and Pyrite?

Differentiating Gold and Pyrite:

Density: One of the key differences between gold and pyrite is their density. Gold has a higher density compared to pyrite, which means it feels heavier in your hand.

Streak: When gold and pyrite are scratched on a rough surface, they leave a streak. Gold leaves a golden-yellow streak, while pyrite leaves a greenish-black streak.

Geochemical Signature: Advanced techniques like inductively coupled plasma mass spectrometry or Fourier transform infrared spectroscopy can be used to analyze the geochemical signature of gold and pyrite, helping to differentiate between the two based on their elemental composition.

Additional Properties: Other properties that can be used to differentiate pyrite from gold include their color, behavior when heated, and hardness. Real gold is made of the same kind of atoms and is heavier, while pyrite is lighter in color, less dense, and harder than real gold.

In conclusion, by examining a combination of properties such as density, streak, and geochemical signature, it is possible to distinguish between gold and pyrite and avoid being fooled by the deceptive appearance of "fool's gold."
