Manganokukisvumite is a rare member of the labuntsovite group typically found as small, pale pink prismatic crystals in alkaline pegmatites. It is primarily a collector's species, valued for its complex chemistry and limited global distribution in the Khibiny Massif of Russia.
Is this manganokukisvumite?
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 manganokukisvumite with a known reference. Manganokukisvumite 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. Manganokukisvumite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Manganokukisvumite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: pink, pale pink.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip
Look in alkaline pegmatites country — that is the host setting where manganokukisvumite typically forms. If you start seeing aegirine, microcline, nepheline 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.
