Panunzite is a rare potassium-sodium aluminosilicate mineral that forms a series with kalsilite and nepheline. It is typically found as microscopic grains in alkaline volcanic rocks and requires precise analytical methods for field identification.
Is this panunzite?
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 panunzite with a known reference. Panunzite sits at Mohs 6, softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Panunzite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Panunzite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: colorless, white.
- 5Look at form & habitCrystal system: hexagonal. Typical habit: massive, anhedral grains.

Field-hunting tip
Look in alkaline volcanic rocks country, the host setting where panunzite typically forms. If you start seeing nepheline, kalsilite, leucite in float, you are in the right ground. Field specimens usually show a massive, anhedral grains habit, so train your eye for that shape before scanning the outcrop.
