Gold does not tarnish* What people might believe is tarnish on their white gold jewellery is actually the natural colour of the white gold coming through.
So, does white gold tarnish? Factors That Cause White Gold To Tarnish. As we've discovered, rhodium-plated white gold doesn't tarnish, but it appears to change color. Over time, the rhodium plating providing that signature bright-white color wears down, revealing the yellow gold underneath.
The answer is yes; white gold can tarnish, but it's a bit more complex than tarnishing seen in other metals. Tarnishing of white gold occurs due to a reaction with various chemicals, both at home and in the environment.
Unlike other precious metals, white gold doesn’t tarnish. That said, its color can fade thanks to the habitual weathering that rubs away its rhodium coating. In this blog, we’ll look at why this happens and some easy steps you can take to keep your white gold pieces shining. What Is White Gold?
White gold is pure yellow gold mixed with other metals (like pure silver and pure palladium) to give it a silver hue. It is tarnish-resistant but has a slight yellow hue because its made of yellow gold.
Pure gold is 100% tarnish-resistant, but most other metals aren’t. Meaning that the lower purity a gold alloy is, the more likely it will tarnish. Genuine 14k and 18k white gold are generally resistant to tarnishing, and if tarnish does occur, it can be removed without damage to the jewelry.
Unlike silver or brass, white gold does not tarnish in the traditional sense, which refers to the metal oxidizing and changing color. White gold's resistance to tarnish is due to its composition, which is typically an alloy of gold mixed with metals such as palladium or nickel to give it strength and its distinctive white hue.
Unfortunately, white gold can tarnish and appear yellowish, brownish, or greenish. It may also turn black. This is because the rhodium plating is not waterproof. It can resist minimal exposure to water but continuous contact will result in tarnished jewelry. It is essential to properly take care of and maintain white gold jewelry.
Unlike silver, which is known to tarnish easily, white gold doesn’t tarnish due to its composition and surface treatment. The alloys (mixtures) of white gold are less reactive than silver and do not readily form compounds with the sulfur compounds in the air, which causes tarnishing.
Yes, white gold can tarnish over time. White gold can tarnish from other metals like nickel in the alloys, which can oxidize on exposure to air and moisture. This oxidation can create a dull or discolored layer on the surface of the jewelry.
