Native nickel is an extremely rare element in nature, most commonly found as terrestrial grains in ultramafic rocks or within iron-nickel meteorites. It appears as a silvery-white metallic mineral that is often associated with serpentine group minerals. Because it is highly susceptible to oxidation, pure native specimens are prized by collectors and researchers alike.

Is this nickel?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

  • 1
    Test the hardness
    Try to scratch nickel with a known reference. Nickel sits at Mohs 4 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Nickel leaves a metallic gray streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Nickel typically shows a metallic luster.
  • 4
    Match the color range
    Compare against the expected color range: silver-white, gray.
  • 5
    Look at form & habit
    Crystal system: cubic. Typical habit: massive, rounded grains, rarely cubic crystals.

Field-hunting tip

Look in ultramafic igneous rocks, serpentinite country — that is the host setting where nickel typically forms. If you start seeing heazlewoodite, magnetite, chromite in float, you are in the right ground. Field specimens usually show a massive, rounded grains, rarely cubic crystals habit, so train your eye for that shape before scanning the outcrop. In the U.S., the densest reported localities are in Nevada, Tennessee — start trip planning there.

Common questions

How do you identify nickel?+
Mohs hardness is 4. It typically shows a metallic luster. The streak is metallic gray. Common colors include silver-white, gray.
Where is nickel found?+
Notable localities include Sudbury Basin, Canada; New Caledonia; Russia; Australia.
Can I find nickel in the United States?+
RockHoundR maps 2 nickel rockhounding spots across 2 U.S. states — the top states are Nevada, Tennessee.
How much is nickel worth?+
Typical asking prices fall in the range of $50-500 depending on specimen size and purity. Quality, size, and provenance can move individual specimens well outside that range.
What rocks look like nickel?+
Nickel is most often confused with Iron. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with nickel?+
Nickel commonly co-occurs with Heazlewoodite, Magnetite, Chromite, Serpentine. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does nickel form in?+
Nickel typically forms in ultramafic igneous rocks, serpentinite. Working float back to the host body is the standard way to chase a fresh occurrence.
What is nickel used for?+
Nickel is used in industrial, scientific.
