Lustre of gold is epitomised in 18 Karat jewellery produced in several eye pleasing tints. Let me give you a bird’s eye view of how 18K jewellery is mesmerizing men and women with various shades:
What is 18 Karat Gold?
Proof gold boasts 99.99 % fineness or purity and commonly known as 24 Karat gold. To make durable, long lasting and vivid colour jewellery the purity has to be reduced to 75.00% by alloying with other metals. The purity of gold has to be kept constant at 75% to be qualified as 18K. What varies is the type of alloy and the proportion in which these are mixed to obtain different shades of colour. Here is a list of ten such shades:
1. Yellow gold: Bright yellow, pale yellow, pink yellow and greenish yellow are tints obtained by mixing silver, copper and zinc in different proportion
2. White gold: Mixing platinum or palladium at about 25% brings dull whitish sheen. Zinc is added as whitening agent. Alternatively, mixture of palladium 17%, silver 4% along with an alloy of metals including zinc for the balance brings out much brighter white gold. In both cases rhodium plating is used to preserve whitishness for a considerable period
3. Grey White gold: The colour of overcast sky is arrived at by mixing iron at 17% and copper at 8% suitably adjusting for a manganese alloy
4. Red gold: This is the straight product after mixing almost 25% of copper suitably adjusting for zinc
5. Pink gold: Pinkish glint is the product of the mixture of 20% copper and 5% silver after making provision for zinc with a pinch
6. Rose gold: This pleasing colour is found by mixing copper at 22.25% and silver at 2.75% with an appropriate dose of zinc
7. Light Green gold: This soft colour is made after mixing silver 23% and cadmium 2%; zinc is added in moderation
8. Green gold: Verdant colour is made from a mixture of silver 20% and copper 5% and appropriate quantum of zinc
9. Deep Green gold: Thick sheen of green is arrived at from a mixture of several metals: silver 15%, copper 5% cadmium 4% and zinc 1%
10. Blue gold: Iron at almost 25% with iridium and zinc will do for the blue sheen
Sparkle and brilliance of colour of 18K gold jewellery is one thing and choosing the right shade for you is another issue. What colour and tint is useful to you depends on your liking for the colour as well as on your personal cosmics. Wrong selection of colour brings misery more than draining tour money.
