C) Ductility: Gold is very ductile, and a tiny piece of gold will bend or dent with pressure from a pin or a pointed piece of wood. Tiny pieces of pyrite will break or resist the pressure. D) Sectility: Small particles of gold can be cut with a sharp pocket knife. Small particles of pyrite cannot be cut. Pyrite is called "Fool's Gold" because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak while pyrite's streak is brownish-black.

4 WAYS TO DISTINGUISH FOOL'S GOLD FROM REAL GOLD. SHINE: When you're viewing fool's gold with the natural eye, it will glisten, not shine. The edges will look sharp and it may separate in layers.

In general, the color of both pyrite and gold is yellow. The difference is that pyrite has a brassy yellow while gold is bright to golden yellow. The majority of gold found in nature is alloyed with silver; when the ratio of silver to gold is high, then the combination will show a whitish-yellow hue. 2. Weight: Fool's gold is less dense than real gold, with a specific gravity of 4.9-5.2, compared to real gold's specific gravity of 19.3. This difference in density can be observed by comparing the weight of a piece of fool's gold to an equally-sized piece of real gold; the real gold will feel significantly heavier. Perform a streak test. Scratch the nugget against a white ceramic tile. Look at the streak that the mineral leaves behind. If it is a greenish black color, you've found fool's gold. Real gold produces a golden yellow streak. Test the mineral's hardness. Use the blade of a pocketknife to slice the surface of the specimen.

Gold and pyrite have significantly different specific gravities. Gold is much more "dense" than pyrite, having a specific gravity of 19.1, and pyrite has a specific gravity of around 5. When comparing pieces of gold and pyrite of similar sizes, the gold piece should be much heavier. However, gold often comes in alloys. 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. Pay attention to the structure of fool's gold - pyrite crystals have sharp edges. Color: Although gold and fool's gold are both metallic and yellowish, they are different shades of yellow. Real gold is a bright shade of yellow, whereas pyrite is a more brassy yellow. Fool's gold is also susceptible to tarnishing, which renders the surface an even duller, brassy color.
