Real Himalayan lamps are hand chiselled solid blocks of ancient crystal salts like this attractive example. They have a beautiful pink color, often pinkish orange, due to the high concentration of trace minerals contained within the salt.
Inside the hollowed out middle of the salt rock lamp is a light bulb to generate both light and heat. This is important for their reported benefits and salt lamps won’t work properly without a heat-producing light.
Himalayan salt lamps also come in decorative bowls of crystal salt blocks, with a light and heat source underneath that creates a soft pink glow in any room you place them in.
