Likely halite (rock salt)
Halite, NaCl
AI-generated identification · may be incorrectSmall, colorless to white translucent crystal with a glassy-to-dull luster; halite has cubic cleavage, Mohs hardness 2–2.5, and specific gravity about 2.17. The photo alone cannot confirm the identification; gypsum or another pale mineral is also possible.

Physical properties
Small, colorless to white translucent crystal with a glassy-to-dull luster; halite has cubic cleavage, Mohs hardness 2–2.5, and specific gravity about 2.17. The photo alone cannot confirm the identification; gypsum or another pale mineral is also possible.
Formation & geological history
Halite precipitates as evaporating saline water concentrates, commonly in sedimentary evaporite deposits. Such deposits form in many geological periods, often in restricted marine basins or salt lakes.
Uses & applications
Used for food and chemical production, road de-icing, and mineral collecting; this tiny rough piece has little commercial value.
Geological facts
Halite dissolves readily in water and commonly breaks into cubic fragments; avoid tasting unknown specimens.
Field identification & locations
Look for cubic shape, very soft hardness, and salty taste only when provenance and safety are certain. Evaporite deposits occur worldwide, including major salt beds in North America and Europe.
