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 check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

  • 1
    Test the hardness
    Try to scratch manganokukisvumite with a known reference. Manganokukisvumite sits at Mohs 5 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Manganokukisvumite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Manganokukisvumite typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: pink, pale pink.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: prismatic crystals.

Where rockhounds find manganokukisvumite

Classic worldwide localities

  • Khibiny Massif, Kola Peninsula, Russia

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.
