Types of Gold Colour
Gold in its purest form is of slightly reddish yellow colour. However, it can be used to produce coloured gold in several other shades. We know that gold used to make jewellery is not 24k pure gold. It is an alloy (a mixture) of gold with other metals to make it strong and durable.
Gold can be alloyed with silver, copper, zinc, palladium, and nickel to create the various found gold colours. The most common gold colours are yellow, white and rose, whereas you can also find gold in green and grey colour.
The bright yellow shade of gold is achieved by mixing pure gold with silver, copper, or zinc. The usual composition of 18K yellow gold
is 75% pure gold blended with 12.5% copper and 12.5% silver. Being the purest colour, it is unlikely to cause any allergy on the skin and requires the least maintenance of all the other gold colours. It is the most preferred one since ages for jewellery and coins.
The silvery-white shade of gold is an alloy of pure gold and at least one white metal (generally nickel, silver, or palladium). White gold
can also be created with gold and platinum. A common white gold composition consists of 90% gold and 10% nickel along with copper added occasionally. Like yellow gold, white gold purity is also measured in karats. It is more durable and scratch-resistant than yellow gold. Due to its colour and durability, white gold is sometimes preferred over platinum to create any diamond or gemstone jewellery.
The pinkish hue of gold known as rose gold (or red gold) is alloyed with gold, copper, and silver. A common formulation of 18K rose gold
is 75% of pure gold with 22.25% copper and 2.75% silver. The only difference between red, rose, and pink gold is the amount of copper in it, which is why the names are often used interchangeably. 22 Karat rose gold, being the highest karat version of it is known as crown gold. Due to its copper quantity, rose gold is more durable than yellow or white gold. And because of its durability and pinkish shine, rose gold jewellery is more popular, and is commonly used for engagement rings, bracelets, and other jewellery items.
Green gold (or Electrum) is a naturally occurring alloy of gold and silver and sometimes copper. Silver gives the gold alloy a greenish-yellow appearance rather than green. Cadmium can also be mixed with gold alloys to generate a green colour, but it is not commonly used as cadmium is highly toxic and that might be dangerous for health. The blend of 75% gold, 15% silver, 6% copper, and 4% cadmium produces a dark-green alloy.
Grey gold is usually made from gold combined with palladium and generally comes in 18 karat. Without palladium, it can also be produced in a cheaper way by adding silver, manganese, and copper to the gold in definite ratios.
