Pyrite is harder than gold. While Pyriteâs hardness is 6 to 6.5, gold has hardness around 2 to 3. Pyrite also contains high amount of iron. There is also a big difference in the specific gravity between gold and pyrite.While gold has a specific gravity of 15.6/19.3, pyrite has 5.0.old vs Pyrite. It is easy to make out the difference between Gold and pyrite. They have much difference in their structure, colour, hardness and specific gravity. When comparing gold and pyrite with regard to their colour, both have a metallic lustre but have different yellow tones.
Pyrite, or fool's gold as it is sometimes known, can be distinguished from real gold by its brittleness and hardness as well as the fact that it appears black in powder form. As it is the least chemically active of all metals, gold usually occurs in a free or uncombined state. It is found as nuggets, flakes or dust in gravel and sand deposits along creeks and rivers, but more often gold is recovered from veins (called lodes) in bedrock. Gold is also produced as a by-product of base-metal mines; about one-fifth of Canada's gold production comes from this source.
