Pyrite vs Gold: 7 Field Tests Before You Celebrate

A lot of beginner prospecting traffic starts with the same question: “Is this gold?” The honest answer is usually “maybe, but test it properly.” This guide keeps it field-useful without pretending a photo can confirm mineral ID.

1. Weight in the pan

Gold is dense. In a pan, real gold wants to sit low and move last. Mica can flash brightly but floats and washes around easily. Pyrite can look yellow, but the grains often behave more like grit than heavy, malleable metal.

2. Shape under a loupe

Pyrite often shows angular, crystalline faces. Mica looks like thin sheets. Real alluvial gold is commonly flattened, rounded, or irregular from transport. A cheap hand lens is one of the best beginner upgrades.

3. The pin test

Real gold is soft and malleable. A tiny flake can usually be nudged or dented with a pin. Pyrite tends to crush or break. Do this gently and only on tiny material you can afford to damage.

4. Colour in shade

Gold keeps a warm yellow colour even out of direct sun. Mica and wet quartz can flash hard in sunlight then disappear in shade. If it only looks exciting at one angle, slow down.

5. Black sand context

Gold and black sand often concentrate together because both are heavy. Black sand is not proof of gold, but it tells you the pan is holding heavy minerals. If your “gold” is floating above the heavies, be suspicious.

6. Streak and hardness checks

Classic mineral tests can help, but do them carefully. Pyrite is harder and can leave a dark streak; gold is softer and yellow. Avoid scratching jewellery-grade pieces or specimens you want to keep intact.

7. Repeatable recovery

One shiny speck is not a paystreak. Sample upstream, downstream, inside bends, behind obstructions, and on bedrock cracks. If the colour repeats in the same trap style, the location matters more than a single photo.

Bottom line

Do not declare a find from a screenshot. Pan it slowly, inspect it under magnification, compare behaviour against black sand, and get a second opinion when money or land access decisions are involved.
