Nefedovite is a rare phosphate mineral found primarily in the hyperalkaline pegmatites of the Kola Peninsula. It typically occurs as small, colorless to pale yellow tabular crystals associated with other rare alkaline minerals like eudialyte and aegirine.

Is this nefedovite?

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 nefedovite with a known reference. Nefedovite sits at Mohs 3.5 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Nefedovite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Nefedovite typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: colorless, white, pale yellow.
  • 5
    Look at form & habit
    Crystal system: tetragonal. Typical habit: tabular crystals, massive.

Where rockhounds find nefedovite

Classic worldwide localities

  • Kola Peninsula, Russia
  • Mount Yukspor, Russia

Field-hunting tip

Look in alkaline pegmatites country — that is the host setting where nefedovite typically forms. If you start seeing apatite, nepheline, microcline in float, you are in the right ground. Field specimens usually show a tabular crystals, massive habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify nefedovite?+
Mohs hardness is 3.5. It typically shows a vitreous luster. The streak is white. Common colors include colorless, white, pale yellow.
Where is nefedovite found?+
Notable localities include Kola Peninsula, Russia; Mount Yukspor, Russia.
How much is nefedovite worth?+
