Perite is a rare lead-bismuth oxychloride mineral typically found as small, thin, yellow to brownish-orange plates. It is primarily known from the Långban mines in Sweden, where it occurs within metamorphosed ore bodies. Due to its lead content and scarcity, it is a highly sought-after species for mineralogists and advanced collectors.

Is this perite?

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 perite with a known reference. Perite sits at Mohs 2 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Perite leaves a yellow streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Perite typically shows a adamantine luster.
  • 4
    Match the color range
    Compare against the expected color range: yellow, orange, brown.
  • 5
    Look at form & habit
    Crystal system: tetragonal. Typical habit: tabular crystals, thin plates.

Field-hunting tip

Look in metamorphosed iron-manganese ore deposits country — that is the host setting where perite typically forms. If you start seeing galena, bismuthinite, hematite in float, you are in the right ground. Field specimens usually show a tabular crystals, thin plates habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify perite?+
Mohs hardness is 2. It typically shows a adamantine luster. The streak is yellow. Common colors include yellow, orange, brown.
Where is perite found?+
Notable localities include Långban, Sweden; Kintore Open Cut, Australia; Tsumeb Mine, Namibia.
How much is perite worth?+
Typical asking prices fall in the range of $100-500 for small specimens. Quality, size, and provenance can move individual specimens well outside that range.
Is perite safe to handle?+
It contains toxic constituents. Contains lead; handle with care and wash hands after handling to avoid ingestion or inhalation of dust. Handle with care, avoid grinding or breathing dust, and store separately.
What rocks look like perite?+
Perite is most often confused with Wulfenite, Phosgenite. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with perite?+
Perite commonly co-occurs with Galena, Bismuthinite, Hematite, Calcite. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does perite form in?+
Perite typically forms in metamorphosed iron-manganese ore deposits. Working float back to the host body is the standard way to chase a fresh occurrence.
What is perite used for?+
Perite is used in collector.
