Native silver is prized for its spectacular dendritic and wire-like crystal habits that form in hydrothermal veins. Specimens often tarnish to a dull gray or black over time, but can be cleaned to reveal a brilliant silver-white metallic luster.
Is this native silver?
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 native silver with a known reference. Native Silver sits at Mohs 2.5-3, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Native Silver leaves a silver-white streak.
- 3Read the lusterHold the specimen under a strong light. Native Silver typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: silver-white, tarnish to gray or black.
- 5Look at form & habitCrystal system: cubic. Typical habit: wire-like, dendritic, arborescent, massive, or as scales.
Often confused with
Native Silver vs. its common look-alikes, and how to tell them apart in the field.
How to tell apart: Streak differs, so Native Silver leaves silver-white, Dyscrasite leaves black.
How to tell apart: Streak differs, so Native Silver leaves silver-white, Tetrahedrite leaves black.
How to tell apart: Arsenopyrite is the harder of the two (Mohs 5.5-6 vs. 2.5-3); streak differs, so Native Silver leaves silver-white, Arsenopyrite leaves black.

Field-hunting tip
Look in hydrothermal veins country, the host setting where native silver typically forms. If you start seeing calcite, galena, safflorite in float, you are in the right ground. Field specimens usually show a wire-like, dendritic, arborescent, massive, or as scales habit, so train your eye for that shape before scanning the outcrop.
