Is Your Pyrite Real or Fake?
How to tell genuine pyrite from imitations
The classic question with pyrite is the opposite of most stones: people want to know whether their 'gold' is real gold or just pyrite (fool's gold). The two are easy to tell apart with a few quick tests — and the value gap is enormous.

Common pyrite fakes & look-alikes
- Mistaken for real gold. Pyrite is brassy and sparkly with flat crystal faces; real gold is softer, deeper yellow, and forms rounded nuggets or flakes, not sharp cubes.
- Chalcopyrite / mica. Other brassy or glittery minerals are also mistaken for gold; same tests below apply.
Simple at-home tests
- 1Streak test. Scrape it on unglazed porcelain or rough tile. Gold leaves a yellow streak; pyrite leaves a greenish-black streak.
- 2Hardness / dent. Gold is soft (Mohs 2.5–3) and dents or scratches with a pin; pyrite is hard (6–6.5), brittle, and crumbles rather than bends.
- 3Weight. Gold is extremely dense — a small piece feels surprisingly heavy. Pyrite is far lighter for the same size.
At-home tests are indicative, not definitive — for valuable pieces, get a professional gemologist's opinion.
The bottom line
Greenish-black streak, brittle, light, with sharp cube faces = pyrite. Yellow streak, soft, very heavy, no crystal faces = possibly real gold (get it assayed).
