Dorallcharite is a rare thallium-bearing member of the jarosite group, typically found as earthy yellow coatings or crusts. It is best known from the famous Allchar deposit in North Macedonia, where it forms as a secondary mineral alongside other thallium-rich species.

Is this dorallcharite?

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 dorallcharite with a known reference. Dorallcharite sits at Mohs 2.5-3.5, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Dorallcharite leaves a yellow streak.
3
Read the luster
Hold the specimen under a strong light. Dorallcharite typically shows a dull luster.
4
Match the color range
Compare against the expected color range: yellow, yellowish-brown.
5
Look at form & habit
Crystal system: trigonal. Typical habit: microcrystalline crusts, earthy aggregates.

Classic worldwide localities

Allchar, North Macedonia

Field-hunting tip

Look in hydrothermal mineral deposits country, the host setting where dorallcharite typically forms. If you start seeing realgar, orpiment, lorandite in float, you are in the right ground. Field specimens usually show a microcrystalline crusts, earthy aggregates habit, so train your eye for that shape before scanning the outcrop.
