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 check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

1
Test the hardness
Try to scratch panunzite with a known reference. Panunzite sits at Mohs 6 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Panunzite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Panunzite typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: colorless, white.
5
Look at form & habit
Crystal system: hexagonal. Typical habit: massive, anhedral grains.

How to tell apart: Luster reads vitreous on Panunzite and vitreous to greasy on Nepheline.

Often found alongside panunzite

Minerals reported to co-occur with panunzite. Spotting these in float or country rock is a strong cue you are in the right ground.

Field-hunting tip

Look in alkaline volcanic rocks country — that is 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.

Common questions

How do you identify panunzite?+

Mohs hardness is 6. It typically shows a vitreous luster. The streak is white. Common colors include colorless, white.

Where is panunzite found?+

Notable localities include San Venanzo, Italy; Kipawa Complex, Canada.

How much is panunzite worth?+

Typical asking prices fall in the range of $50-300 per specimen. Quality, size, and provenance can move individual specimens well outside that range.

What rocks look like panunzite?+

Panunzite is most often confused with Nepheline, Kalsilite. A quick hardness test and a streak check separate the look-alikes faster than color alone.

What minerals are found with panunzite?+

Panunzite commonly co-occurs with Nepheline, Kalsilite, Leucite, Augite. Spotting any of these in float or country rock is a useful trip signal.

What kind of rock does panunzite form in?+

Panunzite typically forms in alkaline volcanic rocks. Working float back to the host body is the standard way to chase a fresh occurrence.

What is panunzite used for?+

Panunzite is used in collector.
