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, 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.
