Zaherite is a rare aluminum silicate hydrate mineral that typically forms as white, platy aggregates within hydrothermal veins. It is most recognized for its association with kaolinite-group minerals and its distinct pearly luster.

Is this zaherite?

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 zaherite with a known reference. Zaherite sits at Mohs 2.5-3 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Zaherite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Zaherite typically shows a pearly luster.
  • 4
    Match the color range
    Compare against the expected color range: white, colorless, pale blue.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: platy.

Field-hunting tip

Look in hydrothermal veins country — that is the host setting where zaherite typically forms. If you start seeing quartz, pyrite, kaolinite in float, you are in the right ground. Field specimens usually show a platy habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify zaherite?+
Mohs hardness is 2.5-3. It typically shows a pearly luster. The streak is white. Common colors include white, colorless, pale blue.
Where is zaherite found?+
Notable localities include Zaher, Pakistan; Czech Republic.

Typical asking prices fall in the range of $50-300 per specimen. Quality, size, and provenance can move individual specimens well outside that range.
What rocks look like zaherite?+
Zaherite is most often confused with Dickite, Kaolinite. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with zaherite?+
Zaherite commonly co-occurs with Quartz, Pyrite, Kaolinite. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does zaherite form in?+
Zaherite typically forms in hydrothermal veins. Working float back to the host body is the standard way to chase a fresh occurrence.
What is zaherite used for?+
Zaherite is used in collector.
