Gold is the most widely used metal in the jewelry world, and almost all jewelry can be matched with gold.
But it also has the most names, such as pure gold K gold, color gold, white gold, pure gold, pure gold, 3D hard gold, white K gold, platinum, gold-plated, gold, gold, gilt, and gold, and so on.
The chemical symbol of gold is AU, which is one of the metals we are most familiar with. Because the purification technology is not perfect, we usually call gold with a gold content of more than 99.9% pure gold, also called pure gold. In fact, there is no essential difference between gold and pure gold. At least when it is recycled, it is the same price. The state has banned these names since 2016, and gold with a gold content of more than 99% is collectively referred to as pure gold, in order to prevent merchants from using them. Nouns make money, but some cabinet sisters will still spread this concept orally, pay attention to screening.
The characteristic of pure gold is that it is very soft, and you can bite the mark with your teeth, so it is ok if it is used for ordinary jewelry, but it is not suitable for inlaying. If you use pure gold for inlaying, there will be no small The risk of falling diamonds is very likely that you will wake up and find that your gems are missing.
In order to prevent this kind of tragedy from happening, K gold was born. Adding other metals to the gold not only effectively improves its hardness, but also gives the gold a better color, which not only satisfies the practicality, but also improves the Aesthetics, this toned K gold, also known as color gold, the main colors are pink rose gold, light gold K yellow, and silvery white K white. Jackpot is the commercial name of K gold, which is actually the same thing.
As for the so-called K number, the way to distinguish it is to divide the number before K by 24, and multiply the number obtained by 100 plus the percent sign to get his gold content. The K number of pure gold is 24, so 24K gold and pure gold are the same thing. 18K gold is 75% gold. This is also the most commonly used K gold purity on the market. It is characterized by high hardness and better color. The mainstream colors are K yellow, K white, and rose gold. It is also very convenient to recycle, that is, to recycle according to 75% of the gold price. There is no saying that k gold is not as good as pure gold.

Platinum is more special, because it is a name that is easily confused. I personally think that the real platinum is 18K platinum, and platinum that is very similar to him is sometimes called platinum. This is called very confusing. Some people think that platinum is platinum, and some people think that platinum is 18K white, so when you are not sure what this platinum refers to, you can confirm whether it is platinum.
It should be added that gold is more expensive than platinum.
Conceptual gold such as 3D hard gold and 5G gold has a value preservation rate lower than that of the most controversial diamonds. The value preservation rate is about 30%-40%. At most, diamonds are only half-cut, so buyers who pursue value preservation can pay attention.
