Potassic-mangani-leakeite is an exceptionally rare member of the amphibole supergroup, primarily characterized by its specific complex chemical composition involving lithium and manganese. It is typically found in manganese-rich metamorphic environments and is of great interest to advanced mineralogists and systematic collectors.
Is this potassic-mangani-leakeite?
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 potassic-mangani-leakeite with a known reference. Potassic-mangani-leakeite sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Potassic-mangani-leakeite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Potassic-mangani-leakeite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: dark green, black.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip
Look in metamorphic rocks country — that is the host setting where potassic-mangani-leakeite typically forms. If you start seeing quartz, albite, aegirine in float, you are in the right ground. Field specimens usually show a prismatic crystals habit, so train your eye for that shape before scanning the outcrop.
