How do you measure karat on gold?

How do you measure karat on gold? When it comes to gold and gold jewelry, the gold is measured in carats. This is a device that measures the minimum guaranteed purity. It is because gold is far too soft to be able to form the basis of a piece of jewelry on its own. To achieve sufficient durability and stability, the gold is mixed with metals, which is called a gold alloy.

How to see the carat of the gold?

Karat, K, is a so-called standardized unit that applies internationally. This is stamped on gold jewelry and other items as a guarantee of authenticity and control stamp . The stamp indicates the gold content of your piece of jewellery. The stamp is characterized by different numbers in a rectangular frame. Common types of karat when it comes to gold:

  • 24 Karat - this is the highest percentage of gold that can be purchased and corresponds to 99.9% pure gold or the number 999.
  • 22 Karat - this corresponds to 91.6% gold and the remaining amount is made up of other metals such as copper, silver or zinc. It is also possible to recognize this carat as the number 916.
  • 18 Karat contains 75% pure gold and is commonly found in Swedish goldsmith shops and is recognized as the designation 750.

The list then continues with 14 Karat and 9 Karat as common gold stamps. 14 Karat corresponds to 58.5% gold and 9 Karat contains 37.5% pure gold.


What does the designation 750 mean on gold?

The designation 750 means, as mentioned above, that the jewelry or object in question consists of 18K gold, i.e. 750 thousandths or 75%. This is actually considered to be the strongest and best percentage of gold when it comes to creating durable and stable jewelry such as rings and necklaces . This percentage distribution is considered solid and to achieve this result the gold is mixed with other metals such as silver and copper.

Should you find stamps with the numbers 830 or 925, you can be sure that your piece of jewelry is not gold, but rather a gold-plated piece of silver. 950 means that the jewelry is made of platinum, a material that is both more expensive and harder than gold.
