Diamond Jewellery Buying Guide
Diamond jewellery is a big purchase, and two pieces that look alike can have very different prices. These basics help you understand what you are paying for.
The 4Cs
- Cut: how well the diamond is shaped and polished. A good cut gives more sparkle.
- Colour: graded from colourless to light yellow. More colourless diamonds cost more.
- Clarity: how few tiny marks or inclusions the diamond has.
- Carat: the weight of the diamond. 1 carat is 0.2 grams.
Natural or lab-grown?
Lab-grown diamonds have the same structure as natural diamonds but are made in a laboratory, and cost much less. Both are real diamonds, but their value and resale are very different. Always ask which type you are buying, and make sure it is written on the bill.
Which gold for diamonds?
Most diamond jewellery is set in 18K gold, which is strong enough to hold stones safely. 14K is lighter on the budget and harder still. 22K is usually too soft for small diamond settings. See 22K vs 24K vs 18K gold.
Certificates
For larger diamonds, ask for a certificate from a recognised lab. It records the 4Cs and confirms whether the diamond is natural or lab-grown. Small diamonds in pavé or cluster settings are often sold with a jeweller’s guarantee instead.

Questions people ask

Are lab-grown diamonds real?
Yes. Lab-grown diamonds have the same structure as natural diamonds, but they are made in a laboratory and are priced much lower.
Which gold is best for diamond jewellery?
18K gold is the most common choice because it holds diamonds securely. 14K is a lighter-budget option.
