Put cut first
A well-cut diamond sparkles more and can look larger than a poorly cut one of the same weight. It is the last thing to compromise on.

Engagement Ring Budget Guide
How much should you spend on an engagement ring? There is no right number — only the one that feels comfortable for you. This guide shows where your budget goes, where it is worth spending, and where you can save without anyone noticing.
Your budget
Start with comfort, not a formula
An engagement ring should be a joy to give, not a worry to pay for. The best budget is one you have chosen yourself, with a clear idea of what each part of the ring costs. Once you know that, it is much easier to put money where you will actually see it.
Myth
Forget the “months’ salary” rule
You may have heard that an engagement ring should cost one, two or three months’ salary. That idea came from diamond advertising campaigns in the twentieth century, not from any jeweller’s advice. Today most couples simply decide what they are comfortable spending and work from there.
Some set a figure first. Others find a style they love, then see what it costs in different metals and diamond qualities. Both approaches work — what matters is that the number is yours.
Where your money goes
The four parts of the price
The total price of a ring is made up of a few clear parts. Knowing them makes it easy to see where your choices have the biggest effect.
- The centre diamond — usually the largest part of the budget. Carat, cut, colour and clarity, and whether it is natural or lab-grown, all change the price.
- The setting — the design that holds the diamond. Simple solitaires cost less than halos, pavé bands or detailed bespoke work.
- The metal — platinum usually costs more than 18ct gold for the same design.
- The finishing — certification, hallmarking and the craftsmanship that goes into making the ring.
Budget ranges
What to prioritise at each budget
These are not price promises — every diamond is different. They show where to focus so your budget goes furthest.
| Budget | What to focus on | Good to know |
|---|---|---|
| Under £1,500 | A well-made solitaire setting with a lab-grown diamond, or a smaller natural diamond | Prioritise cut for sparkle |
| £1,500–£3,000 | A larger lab-grown diamond, or a natural diamond with a good balance of cut, colour and clarity | Consider a halo or pavé band for extra presence |
| £3,000–£6,000 | More choice of size and quality in natural diamonds, or a statement lab-grown stone | Platinum becomes an easy option |
| £6,000+ | Larger natural diamonds, rarer shapes, or fully bespoke designs | Ideal for a bespoke design from first sketch |
Primo engagement ring settings start from £1,175. Prices include VAT.
Spend smartly
Six ways to make your budget go further
Go just under the round numbers
A 0.90ct diamond can cost noticeably less than a 1.00ct, yet the difference in size is almost impossible to see on the hand.
Choose “eye-clean” clarity
You don’t need a flawless diamond. Many diamonds with small inclusions look perfectly clean without magnification.
Match colour to the metal
Slightly warmer colour grades can look beautiful in yellow or rose gold, which may lower the price.
Consider elongated shapes
Ovals, pears and marquise cuts can look larger than a round diamond of the same carat weight.
Add presence with the setting
A halo or diamond band adds sparkle around a smaller centre stone.
Diamond origin
How natural and lab-grown diamonds affect your budget
Both are real diamonds, graded on the same 4Cs. The main difference for your budget is price for a given size and quality.
| Natural diamond | Lab-grown diamond | |
|---|---|---|
| Price for the same size and quality | Higher | Typically much lower |
| What your budget buys | A smaller stone, or the rarity of a natural diamond | A larger or higher-grade diamond for the same spend |
| Grading | Independently certified (GIA or IGI) | Independently certified (IGI or GIA) |
| Appearance | Identical to the eye once set | Identical to the eye once set |
Metal
How your choice of metal changes the price
| Metal | Price | Good to know |
|---|---|---|
| Platinum | Highest | Naturally white, dense and hard-wearing |
| 18ct white gold | Lower than platinum | Bright white finish; re-plating with rhodium may be needed over time |
| 18ct yellow gold | Lower than platinum | Warm, classic colour that suits warmer diamond colours |
| 18ct rose gold | Lower than platinum | Soft blush tone; a quietly distinctive choice |

Questions
Frequently asked questions
How much should I spend on an engagement ring?
There is no set amount. Choose a figure you are comfortable with, then decide how to balance diamond, setting and metal within it. We can show you options at any budget.
Is the three months’ salary rule real?
No. It came from twentieth-century diamond advertising, not from jewellers’ advice. Your budget should be based on what feels right for you.
What should I prioritise on a smaller budget?
Cut quality first, then a size that suits the hand. A lab-grown diamond or a slightly warmer colour grade can make a big difference to what your budget buys.
Is a lab-grown diamond a good way to save?
It can be. Lab-grown diamonds are real diamonds and usually cost much less than natural diamonds of the same size and quality.
Is platinum worth the extra cost?
Platinum is naturally white and very hard-wearing, which many people value for a ring worn every day. 18ct gold is a beautiful and more affordable alternative.
