Sandia is an Irish brand that designs and creates jewellery in Ireland, inspired by the founder's native country, Venezuela. These brass earrings are nickel and lead free. Care instructions: Always keep your jewellery away from water, moisturizers and creams.  Cleaning: Brass will tarnish over time but a soft cloth and a little bit of brass polisher will make it sleek again. Gold plated chains should not be cleaned or the gold colour will be removed. You can also use a damp cloth for wood, rubber and acrylic.
