Malanite is a rare copper-platinum sulfide belonging to the spinel group. It typically occurs as microscopic anhedral grains associated with other sulfide minerals in platinum-rich magmatic deposits.
Is this malanite?
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 malanite with a known reference. Malanite sits at Mohs 5-6, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Malanite leaves a black streak.
- 3Read the lusterHold the specimen under a strong light. Malanite typically shows a metallic luster.
- 4Match the color rangeCompare against the expected color range: gray, white.
- 5Look at form & habitCrystal system: cubic. Typical habit: anhedral grains.

Field-hunting tip
Look in mafic and ultramafic igneous rocks country, the host setting where malanite typically forms. If you start seeing chalcopyrite, pentlandite, pyrrhotite 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.
