Yangite is a rare lead-manganese silicate mineral primarily found in the Yangsuo Mine in China. It typically forms delicate, needle-like acicular crystals or radiating fibrous tufts that are visually distinctive for their pale blue or white coloration.
Is this yangite?
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 yangite with a known reference. Yangite sits at Mohs ~5, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Streak: white.
- 3Read the lusterHold the specimen under a strong light. Luster: vitreous.
- 4Match the color rangeCompare against the expected color range: colorless.
- 5Look at form & habitCrystal system: triclinic. Typical habit: fibrous, acicular, radiating clusters.

Field-hunting tip
Where it forms: In rhodochrosite-bearing epithermal veins of a polymetallic sulfide deposit. If you start seeing melanotekite, rhodochrosite, helvite in float, you are in the right ground. Typical habit: fibrous, acicular, radiating clusters. Train your eye for that shape before scanning the outcrop.
