White gold cannot turn yellow in a short period of time. Unless, of course, you work with the earth without removing the rings. Jewelry salons give a 2-3 year warranty on gold items. Therefore, if white gold has turned yellow in 2 months after purchase, you are definitely talking about a fake, a low-quality ligature and unreliable plating. You cannot remove the yellowing on your own. There is only one way out: give the jewelry to a jeweler for re-coating.

act delicately;

- The best thing to do is to use regular laundry soap or dishwashing detergent;

- If the ring or earrings have a gemstone, rinse with normal running water or soda water.

It is best to entrust your favorite piece of jewelry to a specialist, who will restore its whiteness by professional means.

Reviews

I have been wearing white gold jewelry for a very long time. If you compare white gold with ordinary yellow gold, the first clearly wins in appearance. The snow-white color always looks expensive and noble. Such products perfectly combine with any style of clothing.

I am afraid to buy white gold, because I might come across a fake. As I learned from conversations with a jeweler I know, there is always a risk of buying not precious jewelry, but an alloy of nickel with other metals. Considering that nickel causes allergic reactions, such a purchase is dangerous.

I used to not really like white gold jewelry because it looked like silver. Why pay more when you can buy silver for the same amount of money? But lately modern jewelers have become very happy: they work the metal so skillfully, giving it glitz and glamour, that the silver pales before the white gold. I also love the jewelry pieces made from combinations of two kinds of the noble metal: white and plain yellow.
