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 checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch nickel with a known reference. Nickel sits at Mohs 4 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Nickel leaves a metallic gray streak.
- 3Read the lusterHold the specimen under a strong light. Nickel typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: silver-white, gray.
- 5Look at form & habitCrystal 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.
