Halite
Halite · Mineral Specimen and Industrial Mineral
Crystal System
Cubic (Isometric), typically forms cubic crystals and massive or granular aggregates.
Mineral Group
Halides
Chemical Formula
NaCl
Formation Process
Sedimentary formation through the evaporation of saline water bodies such as inland lakes and restricted seas.
About This Crystal
A small, translucent to transparent, colorless or white cubic crystal with a vitreous to greasy luster.
Physical Characteristics
Colorless to white with a white streak, perfect cubic cleavage in three directions at 90 degrees, conchoidal to uneven fracture, specific gravity of approximately 2.16, brittle tenacity, and entirely water-soluble.
Optical Properties
Isotropic, singly refractive with a refractive index of approximately 1.544.
Hardness & Durability
Origin Region
Found worldwide in evaporite deposits, notably in the USA (Kansas, Michigan, Texas), Canada, Germany, and Poland.
Hardness & Durability
Mohs hardness of 2, very low durability, highly soluble in water, and sensitive to moisture and humidity.
Care & Maintenance
Keep completely dry, avoid any contact with water, store in low-humidity environments, and clean only with dry methods if necessary.
Rarity & Value
Very common mineral with low commercial value for standard specimens, though large or exceptional clear crystals may appeal to collectors.
Special Characteristics
Extremely soluble in water, exhibits a salty taste, and may display fluorescence under ultraviolet light depending on impurities.
Lore & History
Historically vital for human survival and food preservation as common salt. In traditional metaphysical practices, salt crystals are used for purification, cleansing negative energy, and grounding.
