What is 18-karat gold?

18k gold is the king of metals in the world of jewelry. Among the different types of alloys available, the most exclusive gold jewelry always opts for 18 karats, as it is the ideal composition for creating jewelry, such as gold engagement rings, that stands out for its beauty, quality, and durability.

On the Mumit online store you will find an exquisite variety of 18k gold jewelry designs, based on the latest trends in jewelry, with innovation and elegance as common patterns.

Below, we will tell you everything you need to know about 18k gold, its composition, and its different uses in jewelry.

What are karats?

Gold karats are directly determined by their purity level, which must be treated and mixed with other metals to make it suitable for use in jewelry. Therefore, the number of gold karats expresses the range of purity that we will find in its composition.

Next, we will quickly review the different karat levels that jewelry presents, briefly stopping at each of them.

  • 24 karat gold: 24 karat gold is pure gold, in its most natural state. It is a metal that is not suitable for jewelry as it is not malleable enough, which is why it needs to be combined with other precious metals to be used in jewelry manufacturing.
  • 18 karat gold: Among the different types of gold used in jewelry, 18 karat gold is the highest quality. This type of gold practically does not need any maintenance and differs from modalities with fewer karats by presenting a higher level of resistance, directly related to its purity. Due to its resistance and durability, at Mumit stores you will only find 18 karat gold jewelry.
  • 14 karat gold: In this case, if the gold composition were divided into 24 equal parts, 14 of them would be pure gold and the rest, other precious metals. It is a type of gold that is also commonly used in jewelry, but of lower quality than 18 karat gold.
  • 9 karat gold: Among the three types of gold used in jewelry, this is the one with the lowest percentage of pure gold. And what does this mean? Basically, jewelry made with 9 karat gold requires more maintenance, is less resistant, and its shine and color are not comparable to that of 18 karat gold. Logically, all this happens because its purity level is very low and therefore it is only used in costume jewelry and low-quality jewelry, never in fine jewelry.

The difference between 18 karat gold and 24 karat gold

As we mentioned earlier, 24 karat gold is pure gold, while 18 karat gold contains other precious metals in its composition to make it suitable for use in the manufacture of jewelry pieces.

Pure gold is not a malleable enough metal to be treated in its purest state to make jewelry. That is why it is combined with other metals such as silver or platinum in order to take advantage of its wonderful shine and color for the manufacture of jewelry pieces.

How to know the karats of gold

To know the number of karats of gold in a particular piece of jewelry, you must consult the hallmark. This is a mark that usually appears directly on the jewelry itself or on its packaging and indicates the percentage of purity of the gold used in the manufacture of the piece.

At Mumit, all pieces have a hallmark of 750. This hallmark corresponds to 18 karat gold and represents 75% pure gold.
