White Gold vs. Yellow Gold: The Showdown


Have you ever wondered if there are any differences between white and yellow gold (aside from the obvious)? For most, the choice between yellow gold and white gold is simply personal preference. For others, metal allergies can play an important role in deciding which one to buy. Below are just a few key facts to consider when considering white vs. yellow gold.



White Gold


  • This silvery looking alloy consists of gold and one or more other white metals (nickel, manganese, or palladium). 
  • Eighteen-carat white gold might contain 17.3% nickel, 5.5% zinc, and 2.2% copper.  
  • Alloys typically used in jewelry making are gold-palladium-silver and gold-nickel-copper-zinc (palladium and nickel are the primary bleaching agents).

 
Yellow Gold 

  • Yellow gold is also alloyed with base metals to alter hardness and other properties  (primarily copper). 
  • The lower the caratage, the higher percentage of copper or other base metals. 
  • Eighteen-carat yellow gold contains about 25% copper.



Regardless of the color, both yellow and white gold are measured by karats for purity.
Which do you prefer?
