- Sterling silver is an alloy of silver containing 92.5% by weight of silver and 7.5% by weight of other metals, usually copper. The sterling silver standard has a minimum millesimal fineness of 925.
- 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.
- Gold plating is a method of depositing a layer of gold onto the surface of silver,can prevent silver from oxidation,and improve the luster of silver to make it shining like gold.
- A pearl is a hard object produced within the soft tissue (specifically the mantle) of a living shelled mollusk, pearl jewelry remains a sign of an elegant fashion sense.
