White Gold vs. Yellow Gold
The color of gold is established by the percent of alloy added to the gold. When gold is alloyed with copper, silver, and zinc, the shades of yellow will differ. The less alloy the brighter the gold’s color will be. If gold is alloyed with nickel, copper, and zinc, it turns to white gold. Yellow gold and white gold normally share the same malleability and strength as each other. White gold’s color is comparable to platinum, but these two metals have separate properties and vary widely in cost. White gold can also contain Rhodium, which is a form of the platinum family. This is usually added as a plating which brightens the white color. Because the two are so similar, choosing between the two depends upon a person’s individual taste.
