Costume jewellery and fashion jewellery is jewellery made
of non-precious materials such as goldtone or gold-plated,
silvertone or silver-plated, silver wire, resin, beads,
pearlesque, plastics, wood and leather .
Be aware of tarnish which may occur as a result of oxidation, caused by the interaction
of metal, silver or gold plated costume jewelry with certain elements such as
oxygen or sulfur as well as with certain acids.
To keep your costume jewelry tarnish-free, frequently clean your costume jewelry
in a mild dishwashing liquid diluted in water. Thoroughly dry your silver jewelry
after exposure to water. Store your costume jewelry in a dry container or a plastic
bag with anti-tarnish paper.
You can use fresh, uncontaminated commercial silver dip liquid, only. Use of
a polish cloth, paste or other strong jewelry cleaner is not recommended.
