2, colorful, stylish and generous
18K gold is very rich in colors, and there are basically three colors. The industry calls it k red, k yellow and k white, and consumers call it rose gold, gold and platinum respectively.

Because they are liars and want to make more money!
Haha, this answer is in line with many people's presupposition: international brands make money by marketing, and the cost of materials is not that high at all. Buying pure gold is much cheaper than buying their 18K gold!
Of course, the second half of this sentence is correct, but the first half is not so correct.
18K gold means that the content of pure gold is 75%, and the other 25% is other metals.
First of all, use 18K gold instead of pure gold, because pure gold is too soft and only has one color of gold, which is not suitable for decorative jewelry. Too soft, easy to deform, easy to scratch, for example, Chow Tai Fook's thousand gold, which Chinese aunts like very much, is pure enough, but it will lose its shape when put on, and even the pattern of carving dragons and phoenixes will be worn out, and the original sparkle will become Uribatu.
18K gold is pure gold mixed with other metals to achieve enough hardness to keep the jewelry in perfect shape and luster for a long time.
In addition, different colors can be obtained due to different proportions of doped metals. Usually, the metals involved are silver and copper. If the proportion of silver is higher, you will get 18K white gold; if there is more copper, you will get 18K gold; if there is more copper, it will be rose gold. This is a simple statement, besides silver and copper, there will be a small amount of other metals added.
In addition to the common three colors of 18K gold, 18K gold plus other colors such as green and blue are rare.
Therefore, both international brands and domestic brands have products made of pure gold and 18K gold. But international brands rarely use pure gold. They mainly use 18K gold as the basic jewelry skeleton, and diamonds and other precious stones are embedded in it. Pure gold cannot be inlaid.
In addition, the platinum used for jewelry is not pure platinum, but generally 95% pure Pt950. This is also because pure platinum is not hard enough, but it is much better than gold.
However, do people who buy jewelry still care about pure gold or 18K gold? Do you still care that 18K gold jewelry is more expensive than pure gold? That's a jewelry commodity, not a precious metal, which is meaningless.
For another example, the composition of diamond is pure carbon, and graphite is also pure carbon. The difference lies in the crystal structure. The price difference of carbon with the same purity is 108 thousand miles!
Not a category, there is no need to compare. Jewelry gold and pure gold are two kinds of products.
