Hello Sheila,
Thank you for your review! We hope your time in Barbados was well spent, even if it was only for a short time.
Thank you for your concern. We are aware that all precious metal jewelry is required to have the 925 stamp. If you look around the perimeter of your Big Bim Pendant, specifically on the bottom of the island, you'll see a very discreet 925 engraved.
While our pieces are Sterling Silver based, we do plate with 18k gold or rhodium to emulate that white gold finish. Rhodium also adds a layer of protection to the sterling silver to avoid oxidization and increase its longevity.
We hope this helps to understand a little more about our pieces. Please feel free visit our Jewelry Care page, if you need, for more information on our materials and how to care for them.
See you again soon!
