As a rule of thump, people who are used to wearing White gold jewelry do not usually opt for Yellow Gold and that works the other way round too. This phenomenon has been proved since ages, across countries in both sexes. This brings us to the idea that there exists two kinds of gold, yellow and white but only a few of us are aware of the difference between the two.
Basically, both these gold are not different metals, they are just alloyed with some metals to change their color. Pure gold is present in the proportion of 58.3% in both the cases, the rest is the alloy.
Pure gold is too soft to be used as it is. Therefore other metals must be combined in it to make it tough enough to create a piece of jewelry, such metals are called alloys.
Yellow gold uses the alloy silver, while white gold uses nickel. In addition to that, metals like copper and zinc are added to it to get a white hue. Broadly, there is no big difference in the two; it’s a matter of personal choice and taste.
Gold-nickel alloys are hard and good for making rings and pins while for gemstone settings, gold-palladium alloy is used.
