Sterling silver, or 925 silver, is an alloy made of 92.5% pure silver and 7.5% other metals, usually copper, enhancing its durability and strength. It boasts a bright, shiny appearance and can be easily shaped into intricate designs. While silver mining has environmental impacts, the high recyclability of sterling silver and the rise of ethically sourced silver improve its sustainability. Sterling silver items can last a lifetime with proper care, though they may tarnish over time, which is easily remedied with polishing. Its durability, combined with the ability to repair and recycle, makes sterling silver a sustainable and long-lasting jewelry choice.
