This rustic handmade ring is made with Sterling Silver and Copper, and is approximately 10mm wide and 2mm thick. You can personalize it by engraving a date, name, or message on the silver stamp. Every piece is crafted by hand with only hand-controlled tools, following our 95-year-old family tradition of made-to-order jewelry, and is guaranteed to be of exceptional quality and craftsmanship. You should note that Brass and Copper metals will darken if they are not often worn, touched, or rubbed, but the luster can easily be restored with a small piece of smooth sandpaper or a scotch-brite.
