Mayingite is a rare silver-lead bismuth telluride mineral found primarily in gold-bearing hydrothermal deposits. It is typically identified through polished section microscopy due to its small grain size and metallic white color.
Is this mayingite?
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 mayingite with a known reference. Mayingite 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. Mayingite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Mayingite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: white, gray.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: anhedral grains.

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