As mentioned earlier, 22-carat gold jewelry exists, but only in plain gold materials. While 24-carat gold is bright in color, it also has a warmer tone than most other jewelry, making it more attractive. And because they contain more gold, 24-carat jewelry is slightly more valuable than jewelry of the same weight but of lower purity. The downside of 24-carat gold jewelry is that it can easily break and be scratched.
In addition, since 24 carats is pure gold, it is usually slightly more expensive than 22 carats or 18 carats. With 91.67% pure gold for 22-carat gold versus 75% pure gold, it would be more expensive to buy jewelry made of 22k gold than of 18-carat gold. However, it is less durable than 18-carat gold, which has a higher percentage of metal alloys that change the metallurgical properties of gold and leave a gold alloy that lasts longer. This seems strange, because obviously more work was invested in gold jewelry than in currency, but since a gold coin is a kind of monetary instrument, coins sell for more money.
24-karat gold is also sometimes used for jewelry, but because it's so soft, 24-karat gold jewelry is very rare. So, while higher karat ratings are the most sought after, you can also buy gold jewelry with less gold. Well, it's surpassed by 24 carats, and since 24-carat gold is practically pure gold, 22 carats is the next best form of “almost pure” gold. The latter is a more common version of white gold than the former because metallic alloys mixed with gold are cheaper.
An item made of 22 carat gold is, without a doubt, one of the highest quality gold pieces and is therefore very valuable. If you're looking for the best in gold jewelry, it means you're trying to choose between 18k and 22-carat gold. Since most modern jewelry contains other decorative items, they won't necessarily appreciate the price of gold. To do this, we will analyze the basic concepts of these gold alloys and the reason for the price differences.
Twenty-two-carat gold is composed of 91.7% of pure gold and 2.8% of silver and 5.5% of copper or 5.5% of silver and 2.8% of copper. That said, 18 carat gold is not very cheap and, being the most common version of gold used in jewelry, an alloy with practically the highest percentage of gold given what jewelers use to make the best fine jewelry, 18 carat gold is also valuable and a good option, especially in jewelry manufacturing. But what constitutes the different 18-carat gold alloys: white gold, yellow gold or rose gold? (here we wrote a detailed post on the mixing ratio of gold alloys).
