The Palm Tree necklace is a beautiful landscape of larimar and sterling silver, evoking memories of sunny days on the beach. Take good care of your Palm Tree pendant with the following recommendations from the manufacturer. Wipe down your larimar jewelry with a cotton cloth after each wear. Otherwise, air pollutants, dust, perspiration, perfumes and other natural elements can dull the jewelry?s appearance. Silver settings will naturally tarnish over time, so regular cleaning is essential to keep the tarnish in check. To remove heavier tarnish, wash your silver jewelry with warm water and mild soap. Use a clean, nub-free cotton or flannel cloth. Do not use silver polish or dip style cleaning solutions, as they can remove the antique oxidation on many Marahlago larimar silver pieces. Do not use chemicals or cleaners. We strongly advise against using ultrasonic cleaners, steamers, bleach, ammonia or other chemicals or at-home jewelry cleaning solutions on gemstones. Only clean with diluted mild dish soap and warm water. You can also use boiling water and baking soda to clean your sterling silver jewelry. Your larimar jewelry should be professionally cleaned and inspected once a year to prevent costly repairs or replacements. Avoid wearing your jewelry while doing any manual labor, housework, or activity where it might be subjected to sharp blows or excessive friction. We strongly recommend that you avoid exposure to chlorine, household cleaning chemicals, extreme heat or light, salt water, and perfume. When not in use, always store your Marahlago larimar jewelry in the pouch it came in. Store each piece of your jewelry separately in airtight packaging like a plastic bag to prevent tarnishing and scratching.
