Colquiriite is a rare fluoride mineral originally discovered in the Colquiri Mine in Bolivia. It typically occurs as small colorless to white tabular crystals within hydrothermal vein environments, often associated with fluorite and other sulfide minerals.

Is this colquiriite?

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 colquiriite with a known reference. Colquiriite sits at Mohs 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. Colquiriite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Colquiriite 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: trigonal. Typical habit: tabular crystals, massive.

Where rockhounds find colquiriite

Classic worldwide localities

  • Colquiri Mine, Bolivia

Field-hunting tip

Look in hydrothermal veins country — that is the host setting where colquiriite typically forms. If you start seeing fluorite, quartz, pyrite in float, you are in the right ground. Field specimens usually show a tabular crystals, massive habit, so train your eye for that shape before scanning the outcrop.

Common questions

How do you identify colquiriite?+
Mohs hardness is 3.5. It typically shows a vitreous luster. The streak is white. Common colors include colorless, white.
Where is colquiriite found?+
Notable localities include Colquiri Mine, Bolivia.
How much is colquiriite worth?+

What rocks look like colquiriite?+
Colquiriite is most often confused with Fluorite. A quick hardness test and a streak check separate the look-alikes faster than color alone.
What minerals are found with colquiriite?+
Colquiriite commonly co-occurs with Fluorite, Quartz, Pyrite. Spotting any of these in float or country rock is a useful trip signal.
What kind of rock does colquiriite form in?+
Colquiriite typically forms in hydrothermal veins. Working float back to the host body is the standard way to chase a fresh occurrence.
What is colquiriite used for?+
Colquiriite is used in collector, research.
