What Does Karat Mean?
Karat is a measure of gold purity. Pure gold is 24 karats, 24 parts gold out of 24. In practice, pure gold can be very soft to be useful for jewellery, so it's alloyed with other metals to add durability. The karat number tells you how much of the alloy is gold.
9K gold is 37.5% gold. 14K is 58.3% gold. 18K is 75% gold. The remaining percentage is made up of silver, copper, zinc, palladium, or other metals depending on the colour and intended properties of the alloy.
9K Gold: What It Is and Who It's For:
At 37.5% purity, 9K gold is the minimum legal standard for gold jewellery in the UK and Australia. It's harder and more scratch-resistant than higher karats due to the higher alloy content, and it's significantly cheaper.
The trade-off: the colour is noticeably different to higher karats: a yellower, slightly warmer tone in yellow gold, less bright in white gold. Over time, 9K gold can be more prone to tarnish in certain alloy compositions, particularly in humid climates. In Dubai, this matters.
9K is a legitimate choice for everyday pieces where budget is a significant constraint. It is not a fine jewellery standard, and it shouldn't be sold as one.
14K Gold: Real Gold for the Everyday
At 58.3% purity, 14K sits in a practical middle ground. It's more durable than 18K, slightly more affordable, and holds up well to daily wear, which makes it a genuinely good choice for everyday pieces like stacking rings, earrings, or bracelets that take a knock. The colour reads close to 18K in most alloys, and for white gold specifically, the lower gold content can actually produce a better natural colour without rhodium.
For fine jewellery, and engagement rings in particular, we work in 18K. The higher gold content carries more intrinsic value, a richer colour, and the standard expected of a piece built to last a lifetime.
18K Gold: The Fine Jewellery Standard
At 75% gold, 18K is the benchmark for fine jewellery. The colour is the warmest and richest of all the working karats. The material is softer than lower karats, which means it will accumulate character through wear, but structurally sound for settings and constructions that are properly made.
In Dubai, 18K is what the market expects from fine jewellery. It's the standard for engagement rings, wedding bands, and any piece intended to hold stones of value. The higher gold content also means the melt value tracks the gold price more closely - relevant if you're thinking about jewellery as an asset.
22K: The Gold of the Gulf.
At 91.7% purity, 22K is the gold of the Gulf. In Arab culture, gold jewellery has historically been held as a store of wealth as much as an adornment, and 22K reflects that. The colour is deep, saturated, and unmistakably gold in a way that lower karats can't replicate. It's softer and less suitable for complex stone settings, but for pieces where the gold itself is the point, it's extraordinary. It's the karat we use for our posy rings, simple, intentional bands where the material deserves to speak without distraction.
24K: The gold standard - literally.
Pure gold. 99.9% and quite tricky to wear as jewellery in any practical sense, as it's too soft to hold its shape, too reactive to daily life. You'll find it in bullion, investment coins, and some decorative work. It's worth knowing about for investment, but we tend to not use in jewellery.
Gold Plated: What You're Actually Getting
Gold plated jewellery is a base metal. usually brass or sterling silver, with a thin layer of gold deposited on the surface. The gold layer is typically between 0.5 and 2.5 microns thick.
It looks like gold. It costs a fraction of gold. And it wears off. The timeline depends on the thickness of the plating, how often the piece is worn, and what it's exposed to but plating does not last.
Gold plated jewellery is fine for what it is: affordable, accessible, on-trend pieces with a limited lifespan. The problem is when it's priced or positioned as something more. If a piece is plated, that should be stated clearly and the price should reflect it.
Gold Vermeil: Plating With a Higher Standard
Vermeil (pronounced ver-may) is a specific type of gold plating over sterling silver. regulated in several countries to require at least 10K gold plating of at least 2.5 microns. It's a better product than standard plating: the base is silver rather than brass, and the gold layer is thicker.
Vermeil still wears off. It still needs replating. It is still not solid gold. It's a legitimate midpoint for people who want the look of gold without the cost, but it shouldn't be confused with fine jewellery.
Why Solid Gold Is the Only Real Investment
Only solid gold holds its intrinsic value. Plated, vermeil, and gold filled pieces are worth their base metal at melt, which is minimal in comparison to the prices charged at retail. Solid gold pieces are worth their weight in gold, plus the making, plus the stones.
If you are buying jewellery to last decades, to insure at meaningful value, to pass to someone eventually, solid gold is the category that delivers on that brief. Everything else is more in the realm of fashion jewellery, and there's nothing wrong with it as long as that's what you're buying.
