Nowadays, the age level of wearing jade is gradually decreasing, and the requirements for jade jewelry are also very different. Nowadays, people prefer the delicate inlaid, small jade jewelry, and the most common inlaid jade jewelry is 18K gold.
Many consumers think that 18K gold will fade, and they are not willing to choose 18K gold. Then, will 18K gold fade? Is it good to use 18K gold or platinum?
The answer is that 18K gold will not fade! The picture below shows the card!
However, the jewelry I bought will obviously fade. What is going on?
In fact, 18K gold usually has a layer of coating on the surface, and the color drop is due to the "é“‘" of the coating, which shows the original color of 18K gold.
What is 18K gold
18K gold refers to a gold alloy with a purity of not less than 75%, and usually the color itself is yellow. Of course, it is also possible to make rose gold by changing the formula of another 25% of the alloy, for example by adding a high proportion of copper.
Why use 18K gold instead of platinum?
Before answering this question, let's take a look at how the 18K gold jewelry after the discoloration restores the previous light.
The 18K gold after discoloration only needs to be polished and polished on the surface coating, and then re-plated to be as good as ever, with almost no gold loss.
And the cost of gold plating is very low, although the enamel itself is very expensive (the international precious metal price is almost double that of platinum), but the coating requires only a very small amount of bismuth, so the re-plating only costs tens of dollars.
In this way, the 18K gold plating can be solved with little cost, but the platinum is soft, easy to deform, easy to grind, and the loss of re-polishing after grinding is relatively large.
In addition, the hardness of the 18K gold itself is relatively high, and jade such as emerald inlaid is not easily peeled off due to deformation, and the safety of the jewelry is higher.
How to maintain 18K gold
First, separate storage
Putting together with diamonds, jade and other hard-wearing stones may scratch the surface of the K gold, affecting the appearance. So it's best to store it separately, or put it in a jewelry bag and put it with other jewelry.
Second, avoid the environment of excessive cold and overheating
The metal has the characteristics of thermal expansion and contraction. Putting 18K gold in a cold or overheated environment may cause the metal to suddenly shrink or expand, which will affect the firmness of the inlaid jade and may cause some significant losses.
3. Do not wear a ring when exercising or doing housework.
In sports and housework, you may inadvertently rub and bump, causing damage to 18K gold. At the same time, sweat and oil will make the 18K gold slowly turn yellow and lose its brilliance, as well as the inlaid jade.
Fourth, wash hands, make-up, spray perfume, avoid contact when swimming
These acidic or alkaline substances can cause damage to jade and 18K gold. When you swim, you should also take off rings, necklaces and bracelets, because chlorine water will damage the surface of 18K gold.
So everyone should not misunderstand 18K gold, and people are quite wronged.
