There are some dos and don't with keeping your Pearls at their best.  Do clean with a soft cloth after every time you wear them. Don't wipe them with a wet cloth very often.  Do let them dry thoroughly after wiping. Do lay them down to store them. Don't hand them as they will stretch out. Do put them on last and take them off first. Don't spray perfume or apply makeup with them on, as the oils may damage them. Do wear them often. Please don't keep them in too dry an environment as they need moisture to stay supple.
