Is this paravinogradovite?

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 paravinogradovite with a known reference. Paravinogradovite 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. Streak: white.
  • 3
    Read the luster
    Hold the specimen under a strong light. Luster: vitreous to pearly.
  • 4
    Match the color range
    Compare against the expected color range: white.
  • 5
    Look at form & habit
    Crystal system: triclinic. Typical habit: prismatic.

Where rockhounds find paravinogradovite

Classic worldwide localities

  • Mount Kukisvumchorr, Khibina alkaline massif, Kola Peninsula, Russia (type locality)

Field-hunting tip

Where it forms: On albite in miarolitic cavities within a pegmatite at the contact between a xenolith of corundum-bearing hornfels and enclosing foyaite in an alkaline massif. If you start seeing nepheline, k-feldspar, albite in float, you are in the right ground. Typical habit: prismatic. Train your eye for that shape before scanning the outcrop.

Common questions

How do you identify paravinogradovite?+
Mohs hardness is 5. Luster: vitreous to pearly. The streak is white. Common colors include white.
Where is paravinogradovite found?+
Notable localities include Mount Kukisvumchorr, Khibina alkaline massif, Kola Peninsula, Russia (type locality).
What rocks look like paravinogradovite?+
Paravinogradovite is most often confused with Labuntsovite, Nenadkevichite. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with paravinogradovite?+
Paravinogradovite commonly co-occurs with Nepheline, K-feldspar, Albite, Analcime, Natrolite, Aegirine. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does paravinogradovite form in?+
Where it forms: On albite in miarolitic cavities within a pegmatite at the contact between a xenolith of corundum-bearing hornfels and enclosing foyaite in an alkaline massif. Working float back to the host body is the standard way to chase a fresh occurrence.
What is paravinogradovite used for?+
Paravinogradovite is used in collector.
