Sterling silver is a silver alloy which contains 92.5% silver - hence the name. The other 7.5% is comprised of metals which add strength to the otherwise delicate silver metal. .925 sterling silver is the best metal alloy in that it contains the most silver along with the smallest amount of other metals possible to keep the silver from scratching or breaking. All of our sterling silver pieces are marked with “.925” to showcase their authenticity - we’re not about selling fake silver. In fact, all genuine sterling silver jewelry should have a .925 sterling silver stamp. After all, wearing jewelry that’s simply plated with silver can cause allergic reactions.
