Angarfite is a rare phosphate mineral discovered in the Angarf-South pegmatite in Morocco. It typically forms as small, yellow-orange prismatic crystals within phosphate-rich zones of complex pegmatites.
Is this angarfite?
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 angarfite with a known reference. Angarfite sits at Mohs 3 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Angarfite leaves a yellow streak.
- 3Read the lusterHold the specimen under a strong light. Angarfite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: yellow, yellow-orange.
- 5Look at form & habitCrystal system: monoclinic. Typical habit: prismatic crystals.

Field-hunting tip
Look in granite pegmatites country — that is the host setting where angarfite typically forms. If you start seeing quartz, albite, muscovite 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.
