Västmanlandite-(Ce) is a rare cerium-dominant mineral within the vesuvianite group, first discovered in the skarn deposits of Västmanland, Sweden. It typically occurs as small prismatic crystals and is physically similar to standard vesuvianite but distinguished by its rare-earth element composition.
Is this västmanlandite-(ce)?
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 västmanlandite-(ce) with a known reference. Västmanlandite-(Ce) sits at Mohs 6-7 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Västmanlandite-(Ce) leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Västmanlandite-(Ce) typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: brown, reddish-brown.
- 5Look at form & habitCrystal system: tetragonal. Typical habit: prismatic crystals.

Field-hunting tip
Look in skarn country — that is the host setting where västmanlandite-(ce) typically forms. If you start seeing calcite, diopside, garnet in float, you are in the right ground. Field specimens usually show a prismatic crystals habit, so train your eye for that shape before scanning the outcrop.
