Coming from the Khewra Salt Mines in Punjab, Pakistan, these ancient salt crystals date back 600 million years, out dating the Jurassic period of the dinosaurs by 400 million years. The mineral composition of Himalayan Salt gives it its distinctive colour, whereby a distinctive ratio of minerals alters the physical structure of the compound. This composition of minerals refracts light in a beautiful pinkish hue. The result is a soft vibrant light that helps with relaxation.
