Gold consists of absolutely 99% gold, which is more valuable and heavier. After all, the more gold, the heavier jewelry, and 18k gold will be mixed with various precious metals such as silver, platinum and copper. 18k gold will be slightly blue if mixed with platinum, and red if mixed with copper.

2, 18k difference between gold and gold 2: different wearing feel.

The golden one feels bad and has a heavy feeling. However, the quality of 18k gold is not so high, and it is very comfortable to wear. In addition, when mixed with other substances, 18k gold is softer and less hard than pure gold. So when you buy it, you are also advised to buy 18k gold, if it is just for wearing or showing off.

3. The difference between 18k gold and gold is three: the price is different.

This is inevitable. Gold has super high value. The higher the proportion, the higher the value of gold, and the gold with good fineness. You can bite with your teeth. If you can bite, it means gold. You can also use this method to check when you buy it. If it doesn't bite, it means it's alloy.

4. The calculation method of K gold is to divide pure gold into 24 parts. 24k gold is pure gold, but it is actually impossible to have 100% gold. Therefore, the state stipulates that gold with a content above 99.6% can be called 24K gold. Gold jewelry below 9K cannot be called gold jewelry. Even so, if the 18k gold on the market is converted into a gram unit price, the price per gram is much higher than the gram unit price of gold.

5. Under normal circumstances, the recovery price of K gold needs to refer to the international gold price of the day. K gold with different gold contents is multiplied by the gold price to get the recovery price of K gold. For example, the recovery price of gold on that day is 400 yuan/gram, then the recovery price of 18K gold is extremely 400* 18/24=300 yuan/gram. 24k gold is often considered as pure gold, which is "1000‰", but the actual gold content is 99.99%, which is converted into 23.99%.

14k = 14 * 4. 166% = 58.324%(583‰)

18k = 18 * 4. 166% = 74.998%(750‰)

20k = 20 * 4. 166% = 83.320%(833‰)

2 1k = 2 1 * 4. 166% = 87.486%(875‰)

22k = 22 * 4. 166% = 9 1.652%(9 16‰)

24k = 24 * 4. 166% = 99.984%(999‰)

1. Compared with pure gold, 18k gold is much harder than pure gold, so it is more suitable for making all kinds of jewelry. If you want to use the same amount of gold to make necklaces with the same length, gold necklaces are easier to break than 18k kK gold. If we want to achieve the same effect, we must increase the gold content. So it seems that the unit price per gram is higher than pure gold, but in fact, the use value that one gram 18k gold can bring to people has become higher.

2. Gold is soft, so it is hard to bear too fine processing technology. Therefore, gold is mainly used to make traditional jewelry, such as dragon and phoenix bracelets, gold necklaces and pendants. These jewels are usually not easily deformed and damaged. But 18k gold is different. Its hardness is much higher than that of gold and its ductility is strong. It is very suitable for fine processing, so its craft has higher added value than pure gold jewelry.

It is more fashionable than gold jewelry, and exquisite K gold jewelry is more popular. In terms of design style, K-gold jewelry has various postures. You can choose different styles to express your mind and temperament according to your own conditions.
