Romantic Heart Shaped Himalayan Salt Lamp Hand Carved generates negative ions into the air causing home air purification and a feeling of natural environment. Higher light settings emit more negative ions due to increased salt temperature, and help to clear the air of allergens, dust, pollen and other impurities. It brings divine harmony to any room, office or other places. The unique work of art is handcrafted, very attractive, durable, and has a very pleasant scent. The Double Heart Himalayan Salt Lamp includes hand carved salt rock crystal in the form of a double heart shape. Appearance of each Himalayan salt lamp heart varies according to concentrations and positions of mineral veins and deposits. The Himalayan pink crystal salt lamp itself is created by drilling a shaft into the bottom of the rock salt for insertion of the light fixture and screwing it securely to a high quality wooden base.
