Keep your hometown close to your heart with a mini state necklace that is a great way to rep your state! Gold Filled is a delicate product and does tarnish. To ensure your continued enjoyment of your Moon and Lola jewelry it is best to store your jewelry in sealed bags to slow oxidation (tarnishing) of the metal. A gentle polishing cloth works well to remove oxidation. Moon and Lola jewelry should never be dipped in liquid jewelry cleaner. Do not apply lotions, hair products, and/or perfumes etc. while wearing. These products may damage or increase the tarnishing rate of your beautiful jewelry. An occasional gentle soap (such as Dove) and water wash and thorough rinse in tepid water will remove natural skin oils, which can cause dulling or oxidation.
