Florencite-(Ce) is a rare phosphate mineral often found as small, sharp rhombohedral crystals in metamorphic environments or alluvial sands. Collectors typically search for its distinct crystal habit and color, often associating it with quartz or kyanite in high-pressure geologic settings.

Is this florencite-(ce)?

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 florencite-(ce) with a known reference. Florencite-(Ce) sits at Mohs 5-6 — softer than the next harder reference, harder than the previous one.
  • 2
    Check the streak
    Drag the specimen across an unglazed porcelain plate. Florencite-(Ce) leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Florencite-(Ce) typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: yellow, brown, pink, white, colorless.
  • 5
    Look at form & habit
    Crystal system: trigonal. Typical habit: rhombohedral crystals, sometimes pseudo-cubic.

Field-hunting tip

Look in hydrothermal veins, metamorphic rocks, and heavy mineral concentrates in alluvial deposits country — that is the host setting where florencite-(ce) typically forms. If you start seeing quartz, kyanite, hematite in float, you are in the right ground. Field specimens usually show a rhombohedral crystals, sometimes pseudo-cubic habit, so train your eye for that shape before scanning the outcrop.
