What Does “karat” Mean in Gold?
What does karat mean in gold?
Karat (K) is a unit used in measuring the purity of gold. This measurement reveals the percentage of pure gold within a jewelry in proportion to its overall weight. Gold karats are available in 10k, 14k, 18k, 22k, and 24k.
Apart from 24k which is 100% gold, other karats contain metal alloys. While other metals are often added to increase the strength of gold, they reduce the gold purity and overall value of the jewelry.
Compare 10k 14k 18k 22k 24k Gold Differences
10k, 14k, 18k, 22k, and 24k gold differ in purity, durability, color, and price. Higher karats possess more gold content, offering richer color but less durability (24k is the softest).
1. Differences in Purity
Gold purity represents the percentage of gold present within a jewelry and this percentage is measured in karats.
The table below shows the purity differences between 10k, 14k, 18k, 22k, and 24k gold:
| Karat | % of Gold | Fraction of Gold | Millesimal Fineness |
| 10k | 41.7% | 10/24 | 417 |
| 14k | 58.3% | 14/24 | 583 |
| 18k | 75% | 18/24 | 750 |
| 22k | 91.7% | 22/24 | 917 |
| 24k | 99.9% | 24/24 | 999 |
2. Differences in Color
Gold has three primary colors, which are yellow gold, white gold, and rose gold. Yellow gold is derived from a mix of gold with sterling silver, zinc, or copper; White gold, on the other hand, forms when gold is mixed with white metals like rhodium, platinum, or palladium; while rose gold is formed by mixing pure gold with copper.
Generally, the deeper the color, the higher the gold purity. For example, 22k yellow gold has a deeper yellow color than 10k yellow gold because it contains less metal alloys.
3. Differences in Durability
When it comes to gold durability, the highest karat (24k) is the softest and less durable while the lowest karat (10k) is the most durable.
This is because 24k is 100% gold with no metal alloy to make it strong enough for jewelry making. 10k gold jewelry contains 41.7% gold with stronger metal components holding a higher proportion of its total weight. This makes it harder, less prone to scratches, and highly sought after for making various jewelry.
4. Differences in Common Uses
24k gold is not suitable for everyday use because it gets damaged easily. However, its bright color makes it revered for statement pieces often set aside for special occasions. 22k gold is a bit stronger due to a little metal presence, making it suitable for creating heirloom pieces.
18k gold is the most popular gold alloy and it’s known for its strength, beauty and fitness for high end pieces. 14k is highly durable, hence why it is used to make jewelry meant for everyday use. Finally, 10k gold being the hardest is used to make everyday jewelry that is frequently exposed to several conditions.
5. Differences in Price
One thing to know about 10k 14k 18k 24k gold prices is that they are valued according to their level of purity rather than durability. A pure 24k gold jewelry is priced higher than a 22k and 18k gold jewelry. Meanwhile, 10k and 14k gold jewelry which are much more durable carries the lowest price.
Gold prices are quite volatile, changing from time to time due to inflation levels and the factors of demand and supply. Below is a chart that contains the current gold prices as of 10th, March:
| Karat | Price per Gram | Price Comparison (Relative to 24k Gold) |
| 24k | $93.82 | Highest (pure gold price) |
| 22k | $86.3 | Very High (approx. 92% of 24k gold price) |
| 18k | $70.4 | High (approx. 75% of 24k gold price) |
| 14k | $56.3 | Mid-range (approx. 60% of 24k gold price) |
| 10k | $39.4 | Lowest (approx. 42% of 24k gold price) |
6. Difference in Maintenance
High karats like 24k and 22k gold are quite delicate; they often require professional cleaning procedures and are better off stored separately to prevent scratches.
Lower karats like 18k, 14k, and 10k gold are not as delicate as 24k and 22k, hence, they can be cleaned within your home. Since they are worn frequently, the cleaning procedure should be done at regular intervals.
