How Much Do Engagement Rings Cost in the UK?

Engagement rings in the UK typically start from £1,000. As an example, our lab-grown diamond engagement rings at Paragon start from around £1,200, without any compromise on quality, cut, or IGI certification. 

The truth is, there's no single correct number. What you spend depends entirely on four things: the diamond's carat weight, its shape, the setting style, and the metal you choose. Understand those variables, and you can make a better-informed decision that suits your budget. 

What Affects the Cost of an Engagement Ring?

1. Diamond Carat Weight

Carat is the single biggest driver of price. A 0.5ct lab-grown diamond will cost significantly less than a 1ct stone of equivalent cut and colour, not because one is lesser, but because larger diamonds are rarer to produce, even in a lab. 

2. Diamond Shape

Round brilliant cut diamonds are the most expensive shape per carat because they require the roughest diamond to be cut away during production. Elaborate shapes like oval, pear, cushion, emerald will often cost less for the same carat weight and can appear larger face-up. An oval diamond in particular has an elongating effect on the finger that many people love. If your partner is drawn to modern, fashion-forward jewellery, an oval solitaire is worth serious consideration.

3. Setting Style

A solitaire: one diamond, one band is the most popular setting option. Halo settings, where smaller diamonds surround the centre stone, will add to the cost but also make the ring appear significantly larger. A pavé band, where tiny diamonds are set into the metal along the shank, sits in between. Setting complexity directly affects the hours of craftsmanship involved, which is reflected in the final price.

4. Metal Choice

The two most popular choices at Paragon Diamonds are 18ct yellow gold and platinum. Platinum is denser, more durable, and naturally white; it won't need replating over time. It also carries a higher price tag. 18ct yellow gold offers a warmer, classic aesthetic.

Lab Grown vs Natural Diamonds: The Price Difference

Lab grown diamonds are chemically, physically and optically identical to mined diamonds. The difference is origin, not quality. And on price, the difference is significant: a lab-grown diamond typically costs 50–70% less than a mined equivalent of the same carat, cut, colour, and clarity.

In practical terms, this means a budget that might stretch to a 0.5ct mined diamond can comfortably reach a 1ct lab-grown stone. 

Every Paragon diamond comes with IGI certification (International Gemological Institute). Each of our lab grown diamonds comes with an IGI report grading the stone independently on cut, colour, clarity, and carat; all the same standards applied to mined diamonds, which are certified by GIA (Gemological Institute of America). 

Paragon also ensures that every diamond is laser-inscribed to verify it is certified. This inscription can only be seen under a jeweller's loupe (magnifying tool) and does not affect the diamond's appearance or light performance. 

Example: A 1ct round brilliant, G colour, VS1 clarity, set in 18ct white gold in the Emily solitaire pavé setting starts at £1,450. A comparable mined diamond ring would typically start above £4,000.

Matching the Ring to Her Style

Choosing the right ring is less about budget and more about knowing your partner. Here's a practical guide:

• If she loves minimal, clean jewellery: The Claudia or Sophia solitaires are the natural choice, nothing distracts from the diamond.
• If she gravitates towards statement pieces: The Bella or Sadie halo settings will suit her, the surrounding stones create drama and sparkle.
• If she wears a lot of gold jewellery: Consider yellow or rose gold settings. All of our engagement rings are available in yellow gold, white gold, rose gold, and platinum. The Emily pavé band, for example, pairs beautifully with warm-toned accessories.
• If she's fashion-forward and follows jewellery trends: An oval or pear-shaped diamond in a solitaire setting is having a major moment; elongated shapes are everywhere right now, and they photograph beautifully.

How Much Should You Actually Spend?

The old three month ring rule was invented for a marketing campaign in the 1980s. It was never a guideline, it was an advertisement. Ignore it.

What matters is choosing a ring that fits your partner's taste and your financial reality. A £1,200 IGI-certified diamond ring is not a lesser proposal. Spending £40,000 doesn't make the moment more meaningful. What makes the difference is the thought behind it.
