I am probably not a good example of best practice pearl care...
Years ago my 21st birthday strand of akoyas was stolen.
I had only had them for a couple of years and used to wear them nearly every day but I had left them at home that particular day because it was hot and I didn't want to sweat into the pearls. Luckily I was wearing my akoya studs at the time and still have them with me today!
Use and enjoy has been my catch phrase ever since and consequently, I am pretty tough on my pearls.
At times I have worn the above earings for weeks at a time, sleeping, swimming, bathing. I rarely admit to this treatment of my pearl earrings, my Mother would be horrified but at least I can say I have enjoyed every minute of them!
They are yours, treasure them, wear them AND look after them!
