When we think of fine jewellery, we think of Gold. It’s beautiful, versatile and desirable.
Gold has been highly valuable throughout history and has been commonly used for things such as jewellery, art and currency. It naturally has a bright yellow colour which is widely considered an attractive precious metal and does not oxidise in water or air. Pure gold (24ct) is very soft – so it is usually alloyed with other metals when used to make jewellery. This affects its strength, flexibility and colour.
Most of you will have seen Yellow Gold and White Gold jewellery – both have been very popular choices over the years, but have you heard of coloured gold? As mentioned earlier, pure gold is very yellow in colour and you can create a whole range of new exciting colours by alloying the gold with other elements.White Gold is created by adding an alloy of white metal, such as palladium. This gives the whiter colour, and is sometimes rhodium plated to give a brighter appearance. One of the most popular coloured golds has to be Rose Gold. This is created using a copper alloy, and creates a very warm and feminine colour. It is becoming ever more popular in modern jewellery. It is also commonly known as Pink Gold or Red Gold. These names are often used to describe the same piece of metal, but there is a slight difference between them - The redder the gold = the higher the copper content. Green Gold is formed using a mixture of yellow gold and silver – it is more of a lime/yellow colour rather than a full on green. Black Gold is popular in jewellery making and can be achieved in a few ways… Sometimes the gold will be electroplated using a black rhodium – this will give a strong black coating. You can also get the black colour by a process called Patination – this is where a coating of sulphur and oxygen containing compounds is applied to the metal. It will produce a sort of black tarnish. You can get a similar darkening effect from controlled oxidisation of the gold. Purple Gold - also commonly known as Violet Gold or Amethyst Gold is fashioned using an alloy of aluminium. Blue Gold can be made using a mixture of Purple Gold and iron, it is often quite grey in appearance. These coloured golds are very brittle, and are usually only used for specialised jewellery.
