The reason silver needs to be combined with other metals is that it is very difficult to make great designs with just pure silver, which is very soft and malleable. A bit of hardness has to be introduced, by adding other metals such as copper. Mexico is the leading producer of silver, followed by the United States, Canada, Australia, Spain, Peru, and Russia. Silver can be found in nature in silver ore, silver ore is a mixture of other metals including silver. Many countries do not require that precious metal items be stamped.
