Pyrite Vs. Gold: How to Identify Real Gold from Fool's Gold

Density and Weight . Pyrite: Much less dense than gold.Pyrite's specific gravity ranges from 4.9 to 5.2, which means it feels lighter when compared to gold. Gold is extremely dense, with a specific gravity of 19.3, making it one of the densest naturally occurring elements. Gold feels much heavier than pyrite when held.
