Understanding Gold Purity
Gold purity is measured in karats (not to be confused with carats for diamonds). Pure gold is 24 karats. The more alloyed metals mixed into it, the lower the karat, but often the higher the durability.
| Karat | Gold Content | Common Use |
| 24k | 99.9% | Pure gold, soft, coins |
| 22k | 91.6% | High-end traditional jewellery |
| 18k | 75% | Luxury daily wear |
| 14k | 58.5% | Fashion and modern jewellery |
Understanding the karat system helps you make a smarter, more personalised choice when shopping for gold jewellery.
18k Gold
18k gold is made up of 75% pure gold and 25% alloy metals like silver, copper, or zinc. This balance allows it to retain the lustre of gold while gaining the durability needed for everyday wear.
Key Benefits:
- Great balance of purity and strength
- Suitable for modern, detailed designs
- A harder alloy, it resists scratching better than pure gold.
22k Gold
22k gold is 91.6% pure gold, mixed with a small percentage of other metals. It offers a richer yellow hue and is commonly used in traditional Indian and Middle Eastern jewellery.
Pros of 22k:
- Beautiful natural colour
- Holds sentimental and resale value
- Preferred for bridal sets and heirlooms
However, its softness makes it more prone to bending or scratching.

Which is More Durable – 18k or 22k?
18k gold is more durable because of its higher alloy content, making it ideal for rings, bangles, and pieces that see frequent handling. 22k gold, while purer, is softer and better suited for occasional or ceremonial wear.
Visual Appeal – Colour and Shine
22k gold has a naturally vivid yellow tone, making it popular in traditional jewellery. Meanwhile, 18k gold can have a variety of tones (yellow, rose, white), which gives designers more creative freedom, like what you see in signature designs.
Affordability and Investment Value
While 22k gold holds a slightly better resale value due to its purity, 18k offers better value for wearable beauty. It’s less costly, yet more wearable, which makes it a smarter lifestyle investment.
Is 22k Gold Better for Traditional jewellery?
Absolutely. For heritage sets, cultural functions, and bridal wear, 22k is often the go-to. It carries a deeper emotional and visual richness and is commonly passed down through generations.
Why 18k Gold is the Best for Modern Jewellery
