Paramelaconite is a rare copper oxide mineral that typically occurs as small, black, pseudocubic crystals. It is best known for its occurrence in the oxidized zones of copper deposits, particularly the famous Copper Queen mine in Bisbee, Arizona. It is highly sought after by collectors for its unusual crystal structure and rarity.

Is this paramelaconite?

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 paramelaconite with a known reference. Paramelaconite 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. Paramelaconite leaves a black streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Paramelaconite typically shows a adamantine luster.
  • 4
    Match the color range
    Compare against the expected color range: black, brownish-black.
  • 5
    Look at form & habit
    Crystal system: tetragonal. Typical habit: pseudocubic crystals.

Where rockhounds find paramelaconite

Classic worldwide localities

  • Bisbee, Arizona, USA
  • Broken Hill, New South Wales, Australia

Field-hunting tip

Look in oxidized copper deposits country — that is the host setting where paramelaconite typically forms. If you start seeing cuprite, tenorite, chrysocolla in float, you are in the right ground. Field specimens usually show a pseudocubic crystals habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify paramelaconite?+
Mohs hardness is 3. It typically shows a adamantine luster. The streak is black. Common colors include black, brownish-black.
Where is paramelaconite found?+
Notable localities include Bisbee, Arizona, USA; Broken Hill, New South Wales, Australia.
How much is paramelaconite worth?+
Typical asking prices fall in the range of $50-500 depending on crystal quality and size. Quality, size, and provenance can move individual specimens well outside that range.
Is paramelaconite safe to handle?+
It contains toxic constituents. Contains copper; wash hands after handling and avoid ingestion or inhalation of dust. Handle with care, avoid grinding or breathing dust, and store separately.
What rocks look like paramelaconite?+
Paramelaconite is most often confused with Tenorite, Native Copper. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with paramelaconite?+
Paramelaconite commonly co-occurs with Cuprite, Tenorite, Chrysocolla, Malachite. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does paramelaconite form in?+
Paramelaconite typically forms in oxidized copper deposits. Working float back to the host body is the standard way to chase a fresh occurrence.
What is paramelaconite used for?+
Paramelaconite is used in collector.
