Gold is a precious metal that is heavily relied on for jewelry making. Due to its soft nature, it is often alloyed with other metals to make it fit for jewelry making. There are different purity levels and the major ones are 10k, 14k, 18k, 22k, and 24k.
In this guide, we will compare 10k 14k 18k 22k 24k gold differences using factors like their purity, color, durability, common uses, price, and maintenance.

What Does “karat” Mean in Gold?
What does karat mean in gold? “Karat” (K) measures the purity of gold, which 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. Pure gold is 24 karats, meaning 24 parts out of 24 are gold. Lower karats like 10K or 14K contain more alloy metals such as copper, silver, zinc, or nickel, which make the metal harder and more durable for 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 jewelry comes in three primary colors: yellow gold, white gold, and rose gold, and each formed by mixing pure gold with different types of metals:
- Yellow gold is a natural warm tone created by blending gold with sterling silver, zinc, or copper.
- White gold has a silvery sheen, made by alloying gold with rhodium, platinum, or palladium.
- Rose gold gets its romantic pink hue from a mixture of pure gold and copper.
These alloy combinations affect not only the color but also the hardness and price of gold jewelry.
How Karat Affects Gold Color?
Generally, the higher the karat, the deeper and richer the yellow tone, since there’s less alloy dilution. For example, 22K yellow gold has a darker, more intense hue than 10K yellow gold, which appears paler due to its higher proportion of base metals.
3. Differences in Durability
Gold’s durability decreases as purity increases. In other words, the higher the karat, the softer the gold.
24K gold, being nearly 100% pure, lacks alloy metals to strengthen it — making it too soft for daily-wear jewelry. It bends and scratches easily, which is why it’s mostly used for investment bars or ceremonial pieces rather than rings or bracelets.
On the other hand, 10K gold contains only 41.7% pure gold, with the rest made up of durable metals like copper, silver, and zinc. This alloy mix gives it superior hardness, scratch resistance, and long-lasting wearability — making it ideal for everyday jewelry like rings, necklaces, and watches.
4. Differences in Common Uses
Each gold karat serves a unique purpose depending on its strength, color, and purity.
- 24K gold is too soft for daily wear, but its brilliant yellow hue makes it a symbol of prestige and purity. It’s often used for investment bars, cultural jewelry, or ceremonial pieces that aren’t exposed to frequent wear.
- 22K gold contains a small amount of alloy, giving it slightly better durability while maintaining a rich golden tone. It’s ideal for traditional jewelry and heirloom designs that hold sentimental and cultural value.
- 18K gold offers the perfect middle ground — luxurious in appearance yet strong enough for fine craftsmanship. That’s why it’s commonly used in high-end jewelry, engagement rings, and custom designer collections.
- 14K gold is highly durable and versatile, making it one of the most popular choices for everyday jewelry. It balances elegance with practicality and withstands frequent wear without losing its luster.
- Finally, 10K gold, the hardest and most affordable option, is best suited for budget-friendly or utility jewelry, such as pieces worn daily and exposed to active lifestyles.
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. As of Nov. 10, 2025, approximate gold values per gram are as follows (based on monex):
| Karat | Price per Gram | Price Comparison (Relative to 24k Gold) |
| 24k | $130.21 | Highest (pure gold price) |
| 22k | $119.8 | Very High (approx. 92% of 24k gold price) |
| 18k | $97.7 | High (approx. 75% of 24k gold price) |
| 14k | $78.1 | Mid-range (approx. 60% of 24k gold price) |
| 10k | $54.7 | 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.
