22ct vs 18ct Gold: What's the Difference?

Out of all the precious metals, gold is arguably the most exquisite, rare, and valuable. Used in technology, medicine, and of course, jewellery, it has been treasured by people for centuries. But, when it comes to selecting your next piece, one question remains: Should I choose 18ct or 22ct gold?

Comparing 22ct vs 18ct, both are high-quality gold alloys that are ideal for crafting beautiful designs, but the difference goes far beyond the number. From colour and durability to style and pricing, each has something unique to offer. Neither is better than the other. The right choice depends on how you want to wear the piece of jewellery, your lifestyle, aesthetic, and cultural preferences.

In this guide, we’ll explore the difference between 18ct and 22ct gold​ to help you find the ring, necklace, or bracelet that suits you best and the story you want to tell. ​

An overview of gold purity

Before we discuss the differences, it’s important to understand exactly what “22ct” and “18ct” actually mean in terms of gold purity.

Pure gold is naturally soft, so it is usually mixed with other metals such as silver, copper, zinc, or palladium to make it stronger, and therefore more suitable for jewellery to withstand everyday wear.

Gold purity is measured in carats (abbreviated as “ct”), which tells you how many parts are gold out of 24. For example:

• 22ct gold contains 22 parts out of 24, making it approximately 91.6% pure gold and marked with the fineness number 916.

• 18ct gold contains 18 parts out of 24, meaning it is 75.0% pure gold with a fineness number of 750.

These purity differences affect the overall metal’s value, colour, and softness. However, it does not impact the retail price of the jewellery as other factors like craftsmanship, gemstones, and complexity contribute to the cost.

In the UK, precious metal jewellery above the 1 gram threshold in weight must be hallmarked by an approved Assay Office before it can be legally described and sold on the market. A gold hallmark is an official stamp that verifies the metal’s purity and can also include information about the manufacturer of the gold item, the Assay Office who tested it, and the date of the hallmarking.

For anyone investing in 18ct gold jewellery or 22ct gold jewellery, these marks offer additional peace of mind, knowing that the item you are buying is a genuine piece of gold.

Five key differences between 18ct and 22ct gold

While gold purity is the main factor that sets 18ct and 22ct gold apart, there are several other differences to consider. Their colour, strength, and design possibilities all play a part in defining the beauty and character of each.

1. Colour

The most immediate difference between 18ct and 22ct gold is colour.

22ct gold:

Because it has a higher proportion of pure gold, this creates a rich, warm and saturated yellow tone that many people associate with traditional gold jewellery. Its vibrant appearance is particularly cherished among Indian, Pakistani, Sri Lankan and Bangladeshi communities, where gold holds deep cultural and religious significance.

18ct gold:

18ct gold has a larger proportion of other metals (25%) that we mentioned earlier. As such, it can produce a slightly softer or less intense yellow appearance compared to 22ct. However, this allows jewellers greater flexibility when creating different finishes and depths of colour, including white gold and rose gold.

If you love classic, regal tones and traditional attire, especially for bridal wear, 22ct gold jewellery is perfect. If your tastes are more modern, or you like designs based around gemstones, then opt for 18ct gold jewellery.

2. Strength

Purity and strength go hand-in-hand: the higher the gold content, the softer the metal is.

22ct gold:

Since 22ct gold contains a purity of 91.6%, it is more malleable. As a result, fine scratches, small dents, and natural wearing around any clasps can develop over time if worn frequently or handled without care. This does not mean 22ct jewellery cannot be worn and enjoyed regularly, but just requires that extra bit of care to last longer.

18ct gold:

The 25% mix of other metals in 18ct gold provides superior structural strength, making it less susceptible to scratches or dents, and able to support detailed designs, fine claws and gemstone settings. For fine chains, single-style bangles, and diamond rings, 18ct gold is often more practical.

So, when deciding between the two, think about how and when you plan to wear the piece. For special occasions like weddings or simply for nostalgic reasons, 22ct suits these beautifully, whereas those with busier lifestyles may benefit from 18ct.

3. Jewellery design & uses

The physical properties of gold have a huge influence on the types of designs that can be crafted.

22ct gold:

Its softness lends itself wonderfully to traditional, high-purity pieces. From thick gents rings and wedding bands, to solid gold bangles, statement necklaces, chains, and ornate drop earrings. 22ct is also very popular for coordinated bridal sets.

18ct gold:

The added strength of 18ct gold provides jewellers with greater versatility for contemporary styles. Slim settings, geometric shapes, and lightweight designs often benefit from its durability. Engagement rings and fine jewellery relying on delicate claws or tension settings to hold gemstones securely are particularly well suited too.

In the end, the choice between 22ct vs 18ct all comes down to the look you love. Traditional, richly detailed designs often shine in 22ct, while sleek, delicate and modern pieces are more commonly created in 18ct.

4. Maintenance

With the right care, both 18ct and 22ct gold jewellery can maintain their natural lustre and sparkle for many years to come. However, 22ct pieces generally require a little more attention because of their softer composition.

To keep your jewellery looking its best:

• Store pieces separately in soft pouches to help prevent scratching.

• Remove jewellery before strenuous activities or heavy manual work.

• Avoid exposing gold to harsh chemicals and cleaning products.

• Clean gently using a soft cloth, warm water and mild soap.

• Have valuable pieces checked by a professional jeweller when necessary.

5. Price & resale value

As expected, 22ct gold has a higher intrinsic value than 18ct. But two pieces of the same weight may have different prices, depending on the cost of materials, labour, brand markup and gemstone usage.

As 22ct jewellery contains a bigger proportion of gold, it could retain a higher underlying precious metal value per gram in comparison to 18ct gold, assuming similar market conditions.

Having said that, gold prices fluctuate due to economic uncertainty, inflation, and supply and demand. Therefore, jewellery should not be viewed as a guaranteed financial investment. Many of our customers choose gold for its heritage, elegance, and emotional attachment.

If you’re comparing prices between 22ct and 18ct, look beyond the headline figure and consider the gold’s purity, weight and quality of each piece to make a fair judgement.

Final thoughts

There is no correct answer. If durability, flexibility, and contemporary designs, and everyday wear matter most, choose 18ct gold. By contrast, if you’re looking for a richer, yellow gold colour, high purity, and prioritise traditional Asian and Indian jewellery, then 22ct gold is ideal.

At Sanjeev, we understand that gold carries different meanings for everyone, and your jewellery should reflect the emotion, sentiment, and style you desire.
