Jeweller gold

Gold jeweller ornaments never get out of fashion, and knowingly because gold also is favorable for the holder, as well as it is beautiful. Pure gold does not react with other elements, does not grow dull, your skin will not be coloured under gold. Sometimes people have an allergy on metals which are combined with gold, but gold seldom is a problem.

Jeweller gold

Gold can be produced almost any form, including tiny threads which not easily break. One ounce of gold can even be unchained in very thin sheet equal to three square metres. From gold jewellers can produce everything that your imagination will wish.

Because of softness pure (24k) gold, as a rule, it fuses with base metals for use in jewels, changing its hardness and plasticity, melting point, colour and other properties. Gold with lower carats, as a rule, 22k, 18k, 14k and 10k, is contained by higher percent of copper and other non-ferrous metals in an alloy. Copper is most often used not precious metal, displaying red colour. Vosemnadtsatikaratnoe gold, contains 25 % of copper, is used in antique and Russian jeweller alloys. Chetyrnadtsatikaratnoe gold - an alloy with the copper, almost identical on colour to certain bronze alloys. Dark blue gold can be made by iron doping, and violet - aluminium, but is manufactured very seldom, except for specialised jewels. Fourteen - and eighteen - carat jeweller alloys of gold with silver have chartreuse colour and are called as green gold. The alloy of white gold can be produced from a palladium or nickel. White 18-karatnoe gold, contains 17,3 % of nickel, 5,5 % of zinc and 2,2 % of copper silvery on appearance. Nickel is toxic, and issue of white gold with nickel is supervised by the legislation in Europe. Alternative alloys of white jeweller gold are accessible on the basis of a palladium, silver and other white metals, but alloys from a palladium cost more expensive, than what use nickel.
