What is the karat of gold and how is it determined?
The karat is a measure used to determine the proportion of pure gold within a piece of gold compared to other metals added to it. The karat is usually expressed by numbers such as 24, 22, 21, 18, 14, etc., where the number represents the number of parts of pure gold out of 24 parts.
How to determine the gold purity
- Gold percentage:
- 24 karat means that the piece is made of approximately 99.9% pure gold.
- 21-karat gold contains approximately 88% pure gold, while the remainder is made up of other metals such as copper or silver to enhance hardness and durability.
- 18-karat gold contains approximately 75% pure gold, with the remainder being metal alloys that increase the piece's durability.
2. Printing or stamping on the piece:
- The karat is often stamped on gold to show the consumer, such as “24K”, “21K”, or “18K”.
- The seal can be found on the inside of rings or the back of necklaces and bracelets.
3. Appearance and color:
- The higher the karat, the purer and deeper the color of the gold. 24 karat is a pure and bright yellow, 21 karat is slightly darker, while 18 karat tends towards a bronze-gold color.
4. Weight and density:
- Pure gold is heavier than alloyed gold, so weight can give a rough sense of the purity of gold when comparing different pieces.
What is the difference between 21-karat gold and 18-karat gold?
When comparing 18-karat and 21-karat gold, several key differences emerge concerning gold content, color, durability, and price, as follows:
- Gold content: The most significant difference is the percentage of pure gold; 18-karat gold contains 75% gold, while 21-karat gold contains approximately 88% gold. This difference directly affects the gold's color, durability, and market value.
- Color: Thanks to the higher gold content, 21-karat gold appears in a deeper and brighter yellow color compared to 18-karat gold, making it an ideal choice for those who prefer gold with a rich and clear color.
- Durability: 18-karat gold is more durable and scratch-resistant due to its higher alloy content, making it more practical for everyday use and jewelry that is constantly being handled.
- Price: The price of gold increases with its purity, so 21-karat gold is generally more expensive than 18-karat gold, keeping in mind that the final price may be affected by design, brand, and market conditions.
Why is it important to know the karat of gold?
Knowing the karat of gold is an essential step for anyone who wants to buy or invest in gold, as the value and price of gold are directly related to its purity and karat. The higher the karat and the greater the percentage of pure gold in the piece, the higher its value and price. For example, a gram of 24-karat gold is more expensive than a gram of 21-karat gold, which in turn is more expensive than a gram of 18-karat gold.
Therefore, understanding the karat is not just knowing a number printed on the piece, but is key to appreciating the true price of gold and ensuring the selection of the most suitable piece in terms of value and quality.
