Bechererite is a rare secondary mineral found predominantly in the oxidation zones of base metal deposits. It typically forms delicate, pearly-white to pale green platy crusts and aggregates on top of host minerals like smithsonite.
Is this bechererite?
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 bechererite with a known reference. Bechererite sits at Mohs 2 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Bechererite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Bechererite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: white, pale green.
- 5Look at form & habitCrystal system: trigonal. Typical habit: platy crystals, crusts.

Field-hunting tip
Look in hydrothermal ore deposits country — that is the host setting where bechererite typically forms. If you start seeing smithsonite, cerussite, hemimorphite in float, you are in the right ground. Field specimens usually show a platy crystals, crusts habit, so train your eye for that shape before scanning the outcrop.
