To maintain a 14k gold mama necklace,you should not expose it to chemicals, perfumes, or lotions as these will cause the metal to tarnish or get damaged. It is recommended to keep it in a jewelry box or a pouch to avoid tangling and scratching. Wipe with a soft dry cloth to clean off oils and dirt and occasionally use a jewelry cleaner or warm water with soap to clean. It is also important to check the necklace once in a while and ensure that no stones or clasps in the necklace are loose. If you take good care of your mama necklace from Narcissus Jewels it will remain beautiful and meaningful for many years.
