When you see a yellowish tint in your white gold jewelry, it's not because of poor quality. Instead, you see the inner layer of gold alloy under the rhodium plating. Because rhodium is applied in such a thin layer, usually only a few microns thick, it can wear off over time.
Pure gold (24K or 999) has a rich, nearly orange-yellow colour, however gold rarely occurs in nature in pure form. It generally grows as a crystal structure including other elements, like silver or copper.
Gold does tarnish and scratch over time. To preserve the luster of your gold jewelry, avoid exposure to household bleach and other cleaning products, which will quickly cause gold to discolor and possibly disintegrate.
If you're not familiar with white gold maintenance, you may be shocked to see a creamy yellow color slowly replacing the bright white color you fell in love with. You might even begin to question the quality of the metal, but even the highest quality white gold turns yellow over time.

Salt and baking soda are a surprisingly effective combination for cleaning gold. When combined, they create a chemical reaction that helps break down tarnish. Use equal parts of each — say, one tablespoon salt and one tablespoon baking soda — as well as a drop or two of dish soap if you'd like, Martin says.
Yellow gold is a very traditional color for both wedding bands and engagement rings, and the stunning yellow color will not change over time. The color doesn't change because when gold is mined, it is naturally a yellow color.
Drop a small amount of liquid nitric acid on that scratch and wait for a chemical reaction. Fake gold will immediately turn green where the acid is. Gold-over-sterling silver will become milky in appearance. Gold will not react to the nitric acid.
Gold itself does not corrode, but its primary alloys of silver or copper will do so (forming very dark chemical compounds) under moist or wet conditions. When someone perspires, fats and fatty acids released can cause corrosion of 14 karat gold, especially when exposed to warmth and air.
Yellow gold is described as such because of its yellow colour which is a result of it being alloyed with silver and copper.
10k, 14k, and 18k Breakdown
Because pure gold is naturally yellow in color, the higher the karat, the more yellow the metal will appear.
Natural acids and chemicals in your skin: This cause is just unavoidable! The oils in your skin will cause the parts of jewelry touching your skin to turn yellow quicker, like the inside of rings. Salt water, chlorine, soaps, detergents, and lotions: All of these will start to wear off the rhodium plating.
The yellow-gold tint seems brighter and richer because 18k gold contains more gold than 14k or 10k gold. Yellow gold is often a blend of pure gold, copper, and nickel, which gives it a warm appearance. Yellow gold is the purest and most natural hue of gold, out of white, yellow, and rose gold.
If your gold piece turns black or green when the vinegar is on it, or if it starts to smoke or fizzle at all when the vinegar touches it, it is most likely not real gold. If your gold piece does not change colors and does not fizzle or react to the vinegar in any way, it is probably real.
Tarnished gold typically has a dull, grayish color and may appear discolored or have darker patches; sometimes, a tarnished gold color can even be greenish. Tarnish in gold results from a reaction to oxygen in the air. The reaction produces gold oxide, which is a black substance.
The Float Test
Place your gold piece into the water. If it's genuine gold, then it will immediately sink to the bottom of the cup. Pure gold is heavy due to its high density – 19.32 g/ ml. If your gold item floats or hovers above the cup's bottom – it's fake or plated gold.
It is a common myth that toothpaste is a good way to clean your jewellery. This is actually false. Toothpaste can damage your diamonds, gemstones, gold and silver. Toothpaste is abrasive and has a hardness of around 3/4 on the Mohs Scale of Hardness.
Acid test.
An acid test can reveal the karat of solid gold jewelry, but it can also show whether jewelry is solid gold or gold-plated. With an acid test, a small sample of the jewelry is removed and exposed to acid to induce a color change. The resulting colors indicate which type of metal the jewelry is made of.
A: Yes, cleaning jewelry with baking soda and vinegar is pretty simple. Mix 1/2 cup vinegar and two tablespoons of baking soda in a small bowl. Allow your jewelry to soak in the white vinegar and baking soda solution for a few hours.
As long as gold filled pieces are well cared for, they can last a lifetime. Gold plated pieces, on the other hand, can last up to a year if kept away from water, wear, and heat. It's also worth mentioning that gold filled pieces with lower karat weight (9-14k) may be more durable than pieces with greater gold content.
Whether or not white gold turns yellow depends on the base alloy, so the gold used underneath the rhodium plating. White gold itself does not change color, and the color will remain the same.
Yes, it can. Even while 18k gold is of greater quality than 14k or 10k gold, it can oxidize and become discolored with time. Take precautions to shield your gold jewelry from the elements and clean your pieces frequently to keep them looking their best for as long as possible.
