Nordite-(Ce) is a rare complex silicate mineral found primarily in the hyperalkaline complexes of the Kola Peninsula. It typically occurs as small, pale yellow to brownish tabular or prismatic crystals embedded within pegmatite matrices alongside other rare earth minerals.
Is this nordite-(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 nordite-(ce) with a known reference. Nordite-(Ce) sits at Mohs 5-5.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Nordite-(Ce) leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Nordite-(Ce) typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, brown, colorless.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: tabular crystals, prismatic, lamellar.

Field-hunting tip
Look in alkaline pegmatites country — that is the host setting where nordite-(ce) typically forms. If you start seeing aegirine, microcline, eudialyte in float, you are in the right ground. Field specimens usually show a tabular crystals, prismatic, lamellar habit, so train your eye for that shape before scanning the outcrop.
