Jewellery Care / Metal Information
Pure silver, or fine silver, is relatively soft and easily damaged, so it is commonly combined with other metals to produce a more durable product. The most popular of these alloys is sterling silver, which consists of 92.5 percent silver and 7.5 percent copper. Although any metal can make up the 7.5 percent non-silver portion of sterling, centuries of experimentation have shown copper to be its best companion, improving the metal's hardness, without affecting its white, silver appearance.
Sterling silver jewellery is hallmarked with a stamp '925' or 'STERLING'.
Sterling silver may oxidise and become dull looking over time. This is a natural reaction to the chemicals in the atmosphere, heat and the body oils of the wearer. Discolouration can usually be removed by using a silver jewellery cleaning cloth. Contact with perfume, hairspray, chlorinated or salt water and cleaning products should always be avoided. Silver is a malleable (soft) metal, and can be scratched if care is not taken.
A selection of Metal & Dust pieces are made with solid sterling silver and plated with 22ct hard gold plating. Gold plating is very thin, and care must be taken to prolong the finish of plated jewellery. Gold plated jewellery is even more delicate than solid gold or sterling silver. Over time and through every day wear, plating can slowly be worn down.
Contact with perfume, hairspray, moisturiser, chlorinated or salt water and cleaning products should always be avoided. Always avoid contact with water. Keep your gold plated jewellery dry, gently clean after wearing with a soft, lint free cloth.
Gold plated jewellery can scratch if care is not taken. Rings may become easily scratched due to contact with hard surfaces and wear of every day life.

24 carat pure gold is too soft for use in jewellery and is alloyed with a combination of base metals, such as silver, copper or zinc, to improve its hardness and durability.
Yellow gold is the natural, warm colour of solid gold.
To produce white gold, the gold is alloyed with metals such as palladium or nickel. Adding white metals is not enough to get a perfect white color, though, and a white gold alloy, which may look dull grey or slightly yellow. This is why it is plated with rhodium, which actually gives white gold jewelry its color and luster.
To produce rose gold, copper is alloyed with the gold. The more copper that is added, the more rose, pink hue the gold will possess.
9ct solid gold is hallmarked with a stamp '375' or '9ct'
18ct solid gold is hallmarked with a stamp '750' or '18ct'
Solid gold jewellery will not tarnish, although over time, with every day wear it may become dull looking. This is a natural reaction to the chemicals in the atmosphere, heat and the body oils of the wearer. Discolouration can usually be removed by gently using a jewellery cleaning cloth.

It is recommended, to remove gold jewellery when swimming, showering, doing the dishes etc. Contact with perfume, hairspray, chlorinated or salt water and cleaning products should be avoided.
