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