Is this deveroite-(ce)?

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

Where rockhounds find deveroite-(ce)

Classic worldwide localities

Alpe Devero, Italy

Field-hunting tip

Look in hydrothermal veins in gneiss country — that is the host setting where deveroite-(ce) typically forms. If you start seeing monazite, synchysite-(ce), anatase in float, you are in the right ground. Field specimens usually show a platy crystals, granular aggregates habit, so train your eye for that shape before scanning the outcrop.
