Voronkovite is a very rare silicate mineral found in the highly alkaline rocks of the Lovozero Massif in Russia. It typically occurs as small, pseudo-hexagonal tabular crystals associated with other rare-earth and zirconium-bearing minerals in pegmatitic veins.
Is this voronkovite?
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 voronkovite with a known reference. Voronkovite 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. Voronkovite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Voronkovite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: colorless, white, pale pink.
- 5Look at form & habitCrystal system: trigonal. Typical habit: pseudo-hexagonal tabular crystals.

Field-hunting tip
Look in alkaline pegmatites country, the host setting where voronkovite typically forms. If you start seeing aegirine, microcline, nepheline in float, you are in the right ground. Field specimens usually show a pseudo-hexagonal tabular crystals habit, so train your eye for that shape before scanning the outcrop.
