Himalayan salt lamps are a type of decorative light that you can purchase for your home. They come carved out of pink Himalayan salt, and there are various health benefits associated with them. You put a light bulb inside of large chunks of pink Himalayan salt to make these lamps. They have a distinct look, and you'll get a pink, warm glow when you switch them on.
A true salt lamp has pink Himalayan salt that gets harvested from Pakistan's Khewra Salt Mine. Salt taken from this mine is widely believed to be millions of years old. However, it's very similar to traditional table salt. The minerals give it the unique pink colouring.
