As white as they come

As white as they come


White gold is not silver. People often times refer to white gold as silver since it appear and feel like the latter. Partly it is true, since in reality white gold is an alloy of gold and another white metal usually silver or palladium.


The combination of silver or palladium eliminates the yellow gold look and creates the rather white silver appearance. But even if it is an alloy, white gold is still measured in Karats just like ordinary gold. Other white metals used to combine with gold include nickel and platinum.


Each metal used to combine with gold yield varying properties. A nickel based gold alloy, for example, creates a strong and hard metal which makes it ideal to be used for rings and pins.


While, white gold-palladium alloys are relatively softer and flexible which make them great for gemstone settings. However, the disadvantage of using white gold-nickel alloy in body jewelry is that is could cause various skin reactions since nickel is not bio-compatible. Some may have very mild reactions to the metal with only mild itchiness and skin rashes. However, these reactions might turn uglier if they lead to infections. It is therefore best to consider your body chemistry first before buying any type of body jewelry.


Now when hear a higher karat white gold, it doesn’t mean the gold is whiter. White gold is a combination of gold and other metals. The color is affected by the properties of the metals we add to gold and not the amount of gold. Basically, white gold can be either nickel-whites or palladium-whites.


The main difference of which is that nickel-white gold have a colder white color wherein the palladium whites’ color is a little warmer. Also it is very hard to achieve a good nickel white unlike with palladium whites which tends to be softer thus easier to process. Because of the price of palladium, however, palladium whites are a little more expensive.
