Braitschite-(Ce) is a very rare hydrated calcium cerium borate mineral typically found in marine evaporite deposits. It usually occurs as small, delicate platy crystals or granular masses embedded within potash or halite beds. Collectors generally look for it in specialized research-grade collections focusing on rare borate mineralogy.

Is this braitschite-(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 braitschite-(ce) with a known reference. Braitschite-(Ce) 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: white.
  • 3
    Read the luster
    Hold the specimen under a strong light. Luster: vitreous.
  • 4
    Match the color range
    Compare against the expected color range: white, colorless, pink.
  • 5
    Look at form & habit
    Crystal system: hexagonal. Typical habit: hexagonal, microscopic crystals, platy.

Where rockhounds find braitschite-(ce)

Classic worldwide localities

  • Cane Creek potash mine, about 13 km southwest of Moab, and in the CC-1 well, about 1.8 km south of that mine, Grand Co., Utah, USA

Field-hunting tip

Where it forms: In anhydrite at the contact with sylvite in a thick sequence of marine evaporites, at a depth of about 1 km. If you start seeing anhydrite, dolomite, halite in float, you are in the right ground. Typical habit: hexagonal, microscopic crystals, platy. Train your eye for that shape before scanning the outcrop.
