Hunchunite is a rare gold-lead intermetallic mineral first discovered in the gold deposits of Hunchun, China. It typically occurs as microscopic inclusions or grains associated with native gold and silver in hydrothermal vein systems.
Is this hunchunite?
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 hunchunite with a known reference. Hunchunite sits at Mohs 3-3.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Hunchunite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Hunchunite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: white, silver-white.
- 5Look at form & habitCrystal system: cubic. Typical habit: anhedral grains, inclusions.

Field-hunting tip
Look in hydrothermal veins country — that is the host setting where hunchunite typically forms. If you start seeing gold, silver, galena in float, you are in the right ground. Field specimens usually show a anhedral grains, inclusions habit, so train your eye for that shape before scanning the outcrop.
