With every purchase I provide a complimentary polishing cloth that is fabulous for sterling silver, bronze, brass, gold, titanium and other metal alloys.
Avoid using the cloth directly on pearls as it can damage their natural luster.
Resin jewelry can certainly be worn in the sunshine, I mean hey, they're made for Florida living, but prolonged periods of direct sunlight, like sitting on your vanity in direct sunlight through a window all day, can cause the resin to degrade and yellow.
