Vránaite is an extremely rare phosphate mineral discovered in the Czech Republic. It typically occurs as small, colorful crystalline aggregates within complex granitic pegmatite environments.
Is this vránaite?
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 vránaite with a known reference. Vránaite sits at Mohs 5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Vránaite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Vránaite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: pink, orange, brown.
- 5Look at form & habitCrystal system: orthorhombic. Typical habit: anhedral grains.

Field-hunting tip
Look in granite pegmatites country — that is the host setting where vránaite typically forms. If you start seeing graftonite, beusite, triphylite in float, you are in the right ground. Field specimens usually show a anhedral grains habit, so train your eye for that shape before scanning the outcrop.
