Is this goldquarryite?

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 goldquarryite with a known reference. Goldquarryite 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. Goldquarryite leaves a white streak.
  • 3
    Read the luster
    Hold the specimen under a strong light. Goldquarryite typically shows a vitreous luster.
  • 4
    Match the color range
    Compare against the expected color range: white, colorless.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: tabular crystals, aggregates.

Where rockhounds find goldquarryite

Classic worldwide localities

  • Gold Quarry mine, Nevada, USA

Field-hunting tip

Look in phosphate-rich sedimentary rock environments country — that is the host setting where goldquarryite typically forms. If you start seeing variscite, wavellite, crandallite in float, you are in the right ground. Field specimens usually show a tabular crystals, aggregates habit, so train your eye for that shape before scanning the outcrop.
