Is this lakebogaite?

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 lakebogaite with a known reference. Lakebogaite 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. Streak: pale yellow.
  • 3
    Read the luster
    Hold the specimen under a strong light. Luster: vitreous.
  • 4
    Match the color range
    Compare against the expected color range: bright lemon yellow.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: blocky, euhedral crystals.

Where rockhounds find lakebogaite

Classic worldwide localities

  • Lake Boga quarry, northern Victoria, Australia

Field-hunting tip

Where it forms: In miarolitic cavities and on joint surfaces in a weathered uranium and fluorapatite-bearing pegmatitic granite. If you start seeing meurigite-na, torbernite, saléeite in float, you are in the right ground. Typical habit: blocky, euhedral crystals. Train your eye for that shape before scanning the outcrop.
