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 checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry 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.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Zaherite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Zaherite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: white, colorless, pale blue.
- 5Look at form & habitCrystal 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.
