Is this escheite?

4-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 escheite with a known reference. Escheite sits at Mohs 4, softer than the next harder reference, harder than the previous one.
  • 2
    Read the luster
    Hold the specimen under a strong light. Luster: vitreous.
  • 3
    Match the color range
    Compare against the expected color range: pink, red, white, yellow.
  • 4
    Look at form & habit
    Crystal system: orthorhombic. Typical habit: massive, granular, rarely prismatic.
