Types of gold
Gold purity is well known as 18K gold and 24K gold, but in fact, a wide range of gold like 9K gold,10K gold,14K gold,18K gold, 20K gold, 22K gold,24K gold also exist. Gold purity is split into 24 minutes fraction, and the higher the number, the higher the purity. Specifically,24K gold means that it contains 24/24 of gold in it, representing the pure gold, which is 100% gold. On the other hand,18 gold contains gold at a rate of 18/24, so the percentage of gold is 75%. The rest of it is made out of metals such as silver or copper, according to the percentage, there will be differences in hardness and color. People usually think that the higher the purity of gold, the better it is. But it depends, it might be better not to use 24K gold in certain particular items.
There are also cases where it will be better when the pureness of gold isn’t too high.
Purity also affects the hardness of the finished product, so depending on the type and design of the product, it may be better not to be too high. For example, high purity 24 gold is too soft and unsuitable for processing jewelry with complex designs. Because it will be easily scratched when it is used practically. So usually accessories are made out with other mixed gold. This point often appears in the difference of preference by countries.
Preference of pureness differs depending on country
In Japan, there are still many people who wear accessories only when they have special occasions, so while relatively pure 18K gold is preferred. In the other hand, western countries where jewelry and accessories are worn well, lower purity gold such as 9K gold,10K gold,14K gold, is often chosen. However, items such as gold coins and ingots, which are more concerned, holds a higher value in any country with the higher purity of gold. While for collections and assets, higher purity will be more important where practicality is not questioned. And for accessories that are intentionally made to be low in purity, to make it harder.
