Store your jewellery in plastic ziplock bags, preferably in an airtight box, away from humidity, moisture, heat, and fire. Keep each piece in a separate ziplock pouch.
Avoid contact with creams, cosmetics, nail polish remover, perfume, hairspray, and water.
Do not store the jewellery in tissue paper, cloth, leather, or velvet pouches.
Wipe away sweat, if any on the jewellery, with a soft cotton cloth after use.
