Parawulffite is a rare volcanic fumarole mineral discovered at the Tolbachik volcano in Russia. It typically appears as attractive dark green to deep emerald green tabular crystals associated with other copper-bearing volcanic minerals.

Is this parawulffite?

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 parawulffite with a known reference. Parawulffite sits at Mohs 3-4, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Parawulffite leaves a light green streak.
3
Read the luster
Hold the specimen under a strong light. Parawulffite typically shows a vitreous luster.
4
Match the color range
Compare against the expected color range: dark green, deep emerald green.
5
Look at form & habit
Crystal system: monoclinic. Typical habit: tabular crystals, subparallel aggregates.

Often confused with

Parawulffite vs. its common look-alikes, and how to tell them apart in the field.

How to tell apart: Streak differs, so Parawulffite leaves light green, Kamchatkite leaves yellow.

Field-hunting tip

Look in fumarole deposits country, the host setting where parawulffite typically forms. If you start seeing wulffite, kamchatkite, tolbachikite in float, you are in the right ground. Field specimens usually show a tabular crystals, subparallel aggregates habit, so train your eye for that shape before scanning the outcrop.
