*It is imperative that Sterling Silver (All precious metal) is properly stored in air tight bags or air tight containers with Tarnish Proof materials. Jewelry must be properly maintained and kept clean due to exposure to oxygen, body chemistry, oils, perfumes/chemicals and perspiration. These may harm this precious metal because it has a very small percentage of copper alloy for stability that may react to such things and become tarnished. Once jewelry is removed from packaging: exposed or worn there is NO refund nor exchange)
