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 checkRun through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.
- 1Test the hardnessTry to scratch colquiriite with a known reference. Colquiriite sits at Mohs 3.5 — softer than the next harder reference, harder than the previous one.
- 2Check the streakDrag the specimen across an unglazed porcelain plate. Colquiriite leaves a white streak.
- 3Read the lusterHold the specimen under a strong light. Colquiriite typically shows a vitreous luster.
- 4Match the color rangeCompare against the expected color range: colorless, white.
- 5Look at form & habitCrystal system: trigonal. Typical habit: tabular crystals, massive.

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.
