Vanuralite is a rare secondary uranium-vanadium mineral typically found as bright yellow platy crystals or thin crusts in the oxidized zones of uranium deposits. Collectors should look for its distinctive pearly luster and association with other secondary uranium minerals in oxidized ore bodies.
Is this vanuralite?
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 vanuralite with a known reference. Vanuralite 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. Vanuralite leaves a yellow streak.
- 3Read the lusterHold the specimen under a strong light. Vanuralite typically shows a pearly luster.
- 4Match the color rangeCompare against the expected color range: yellow, bright yellow.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: platy crystals, radial aggregates, coatings.

Field-hunting tip
Look in oxidized zones of uranium-vanadium deposits country — that is the host setting where vanuralite typically forms. If you start seeing francevillite, curite, kasolite in float, you are in the right ground. Field specimens usually show a platy crystals, radial aggregates, coatings habit, so train your eye for that shape before scanning the outcrop.
