Physical properties
Hardness: 2.0-2.5 on Mohs scale; Color: Pink, orange, or reddish-white; Luster: Vitreous; Crystal structure: Cubic; Cleavage: Perfect cubic; Solubility: Highly soluble in water
Formation & geological history
Formed by the evaporation of ancient seas during the Precambrian or early Paleozoic eras, approximately 250 to 500 million years ago. Found in deep underground mines in the Punjab region of Pakistan.
Uses & applications
Culinary use (gourmet salt), home decor (salt lamps), spa/wellness treatments (halotherapy), and as mineral licks for livestock.
Geological facts
The pink hue is caused by infinitesimal amounts of iron oxide (rust). Despite the name, most Himalayan salt is mined in the Khewra Salt Mine in Pakistan, nearly 300 kilometers from the actual Himalayas.
Field identification & locations
Identified by its distinctive salty taste, cubic cleavage, and low hardness (can be scratched by a fingernail). It will 'sweat' or dissolve slightly in humid environments.
