One is a metal alloy where silver is combined with other metals (typically copper) to increase durability, while the other is a base metal coated with a thin layer of silver. The alloy is typically 92.5% silver, hence the “.925” stamp commonly found on items made from it. The coating involves depositing a thin layer of silver onto a less expensive metal, such as copper, brass, or nickel.
The choice between these materials impacts cost, longevity, and aesthetic appeal. The alloy offers a higher intrinsic value, greater durability, and tarnish resistance compared to the coated alternative. Historically, the alloy has been preferred for valuable objects due to its lasting quality and inherent metal value. The coated option is more economical, making it suitable for decorative items where affordability is a primary concern.
