Why did my beloved colored gold earrings turn black?

Last year, I bought a pair of rose gold earrings, so-called colored gold. I think they are more fashionable than gold, and their styles are very novel, which is better to match clothes.

I bought it for more than a year, but I didn't bother to take it off in the shower, but there was no problem. It is always bright.

I wanted to change my earrings yesterday, so I took them off. Unexpectedly, the root of one earring turned black, but the other one was fine.

I wiped the glasses cloth over and over again, but the blackened place remained unchanged. I really wonder in my heart that the lottery gold I bought before has never turned black. Why is there something wrong with this earring?

I bought it at the Cupid counter in the mall. It stands to reason that the quality of the goods should be guaranteed.

I immediately looked it up on the Internet and found that lottery gold is made of gold and other metals in a certain proportion through color separation electroplating process.

Its disadvantage is that it is easy to change color, and the colorful effect is expressed by the color of the covering layer. But with the passage of time, the rhodium on the surface will slowly wear off, leaking the original color of gold, which is often called yellowing or fading.

Therefore, after buying colored gold ornaments, special attention should be paid to maintenance. Colored gold should not be exposed to acid and alkali chemicals and detergents, including detergent, shower gel and shampoo.

Also, the sweat of the human body itself will also corrode the lottery money. After wearing it, wipe it with a wet towel and then dry it with a dry towel.

I have never followed these precautions. At most, if it is dirty, take it to the gold shop for washing. According to my years of experience, daily shampoo, shower gel, etc. Will not cause black jewelry.

It suddenly occurred to me that the other day, I went to the barber shop for a perm. It is estimated that the chemicals used for perm accidentally dripped on the earrings, which caused the earrings to suddenly turn black.

It is also said on the Internet that if there is a black silver film on the surface of gold ornaments, it can be made into a "gold cleaner" with 2 grams of salt, 7 grams of baking soda, 8 grams of bleaching powder and 60 ml of clear water. After soaking for 2 hours, take it out, rinse it with clear water and then dry it with a soft cloth.

But there is no baking soda and bleaching powder at home, and the shopping mall is close to the unit. Just get it directly to the gold shop the next day and let people handle it!

The waiter in the gold shop asked me doubtfully with earrings, is there a fire? I smiled and said, no, how can it burn if you wear it on your ear every day!

It seems that they have no experience. In fact, I know in my heart that it is caused by improper use, and I dare not say that it is caused by perm!

The waiter asked me to sit on the sofa and wait for a while. She brought it in and dealt with it. After waiting for more than ten minutes, the waiter gave me the earrings and they finally recovered!

Dear friends, it is best not to wear jewelry when perm your hair in the future. Drops of medicine may turn black!

How about my new hairstyle? Colleagues say they look like Hong Kong and Taiwan stars!
