Pandoraite-Ba is a very rare vanadate mineral that typically forms as delicate, thin platy crystals or thin crusts. It is named after the Pandora mine in Colorado, its type locality, where it occurs in oxidized zones of vanadium-bearing deposits.

Is this pandoraite-ba?

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

Field-hunting tip

Look in vanadium-uranium-bearing sedimentary deposits country — that is the host setting where pandoraite-ba typically forms. If you start seeing pascoite, sherwoodite, vanadinite 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.
