Even though this necklace is genuine sterling silver, it is not recommended to be worn in water, in saunas, pools, baths, showers, or during exercising. Avoid wearing during exercise, as sweat will react with the jewelry to produce silver chloride and copper sulfide, which causes the jewelry to deteriorate and corrode over time. We recommend you do not allow lotions and oils to come in contact with your necklace. Again, it is genuine silver, but best practice for silver jewelry is to keep it out of water and away from chemicals.
The same guidelines for genuine sterling silver apply to your genuine moonstone also. When properly cared for, this necklace will last for years to come, and remind the recipient that they are amazing. Thank you.
