Gold
Learn about Gold
Gold won't tarnish, rust, or corrode and though it's very strong, it is also the most malleable of all metals.
Purity
Pure gold is too soft to withstand the stresses of every-day wear, so it is alloyed with a mixture of metals like silver, copper, nickel, and zinc to give it strength and durability. Caratage, noted by a number followed by "ct" indicates purity, or how much of the metal in a piece of jewellery is gold. Caratage in precious metal terms is expressed in 24ths, making 24ct gold 100% gold.
Yellow Gold
Nirvana Diamonds supplies items containing 18ct and 9ct yellow gold. 18ct gold contains more precious metal than 9ct gold. It is composed of 75% gold, which is alloyed with other metals to make it strong enough to withstand every day wear. Because 9ct gold is composed of only 37.5% gold and 62.5% other metals that give it strength, its gold colour is not as rich as 18ct gold. 9ct gold is most commonly found in wedding bands or in cases where strength is most important, like in earring backs and bracelet clasps.

White Gold
Because 18k white gold is 75% gold, and 9ct white gold is 37.5% gold, jewellery made from these metals has a slight yellow colour. Nirvana Diamonds only supply white gold in 18ct form.
