Dravertite is an exceptionally rare sulfate mineral first discovered in the volcanic fumaroles of the Tolbachik volcano in Russia. It typically occurs as small, colorless to white tabular crystals associated with other exotic copper and magnesium minerals formed through volcanic gases.

Is this dravertite?

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 dravertite with a known reference. Dravertite sits at Mohs 3 — softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Dravertite leaves a white streak.
3
Read the luster
Hold the specimen under a strong light. Dravertite 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: orthorhombic. Typical habit: tabular crystals.

Where rockhounds find dravertite

Classic worldwide localities

Tolbachik volcano, Kamchatka, Russia

Field-hunting tip

Look in volcanic fumaroles country — that is the host setting where dravertite typically forms. If you start seeing anglesite, lammerite, tenorite in float, you are in the right ground. Field specimens usually show a tabular crystals habit, so train your eye for that shape before scanning the outcrop.
