Specific Gravity is a measure of the density of a mineral. At times it is such a useful property that it is the only way to distinguish some minerals without laboratory or optical techniques. Gold (pictured) can easily be distinguished from "fool's gold" by specific gravity alone, although there are many other ways.Specific Gravity is a measure of the density of a mineral.

What Is the Difference Between Fool's Gold and Real Gold?

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 Gold and pyrite have significantly different specific gravities.

Fool’s Gold vs Real Gold. There are minerals that bear a close resemblance to real gold, but differ significantly in terms of structure. For example, fool’s gold is not a metal, while real gold is pure metal. Fool’s gold is actually a mineral composed of iron sulfide, with a crystalline structure.Fool’s Gold vs Real Gold.

Fool’s Gold vs. Gold - How to Tell Fools Gold from Real Gold?

Fool’s Gold. Pyrite is widely known as fool’s gold because people often mistakenly consider this widespread mineral for real gold. Many believe that this term appeared for the first time among miners and gold prospectors during the Gold Rush.. In such a case, the most likely reason for this name was that someone felt stupid after trying to sell pyrite they mistakenly considered real gold.Fool’s Gold.
