Whether silver plating or pure silver, the composite of the metal will tarnish when exposed to air and sulfur. Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of corrosion. In the case of silver tarnish, the silver combines with sulfur and forms silver sulfide (Ag 2 S), which is
Jewelry with gemstones such as diamonds or sapphires can be cleaned at home as well using mild soap and warm water. However, gemstones such as opals and pearls should be done professionally. Another issue is the age of jewelry, as certain materials or build strategies of older jewelry (such as from the Georgian era ) may have restrictions, such ...

It constitutes the tarnish that forms over time on silverware and other silver objects. Silver sulfide is insoluble in most solvents, but is degraded by strong acids. Silver sulfide is a network solid made up of silver (electronegativity of 1.98) and sulfur (electronegativity of 2.58) where the bonds have low ionic character (approximately 10%).
Jewelry hygiene is an area of study focusing on sanitary practices and habits relating to jewelry in an effort to understand jewelry's effect on hand hygiene. There are four key elements to optimally sanitizing jewelry: steam or hot water, water pressure and an antibacterial cleaning agent.
The platinum is used to replace at least some of the copper present in a typical sterling silver alloy, which provides a greater light reflectivity (by refining the grain structure) and resistance to tarnish (thought to be caused by oxidation of copper) than standard sterling silver. Platinum Sterling is a cheaper alternative to white gold.
