Konyaite is a rare hydrated magnesium sulfate mineral that typically forms as an efflorescent crust in salt lake environments. It is highly unstable and dehydrates easily into other magnesium sulfate minerals, making it a challenge to preserve in collections without humidity control.

Is this konyaite?

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 konyaite with a known reference. Konyaite sits at Mohs 2.5, 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.
  • 5
    Look at form & habit
    Crystal system: monoclinic. Typical habit: fibrous crusts, efflorescences.

Where rockhounds find konyaite

Classic worldwide localities

  • Found at many places, North Dakota, USA
  • Çakmak, between Ereǧli and Niǧde, Great Konya Basin, Konya Province, Turkey
  • Tǎuçoare Cave, Rodna Mountains, Romania
  • Noted across central and southern, Alberta, Canada

Field-hunting tip

Where it forms: Widespread in salt efflorescences on saline soils, formed between 30°C and 50°C by evaporation of ground and surface waters. If you start seeing gypsum, hexahydrite, blödite in float, you are in the right ground. Typical habit: fibrous crusts, efflorescences. Train your eye for that shape before scanning the outcrop.
