The Rings
How much to actually spend on a ring (UK reality vs the myths)
The two months’ salary rule is an advertising line. It was written to sell diamonds, it has been adjusted country by country to suit local incomes, and it has never had any basis in etiquette, in tradition or in anything a jeweller would recognise as a professional recommendation.
Knowing that is useful but not sufficient, because the question underneath it is real: how much should this cost? What follows is the honest answer, which is that the number is set by what the ring has to do and by what the rest of the wedding needs, and then a set of published prices showing what each level actually reaches.
Where the rule came from
The salary benchmark grew out of the advertising campaign De Beers ran through the agency N.W. Ayer from 1938 onwards, the campaign that also produced “a diamond is forever”. Al Jazeera’s account of how the diamond engagement ring was invented and sold worldwide records the figure being pitched at different multiples in different markets: two months in the United States, one month in the United Kingdom, three months in Japan.
That variation is the tell. A genuine rule about how much a ring should cost would not have three different values depending on which country’s advertising department set it. It is a sales target expressed as advice, and it worked extraordinarily well, which is why it is still repeated by people who have never heard of the campaign.
What should actually set the number
Three things, in this order.
What the ring has to survive. A ring worn daily on a working hand needs a robust setting and enough metal in the shank, and that is a floor rather than a preference. Below a certain build quality the ring will need repair work within a few years, and the repairs cost more than the difference would have.
What the rest of the wedding needs. The ring competes with the venue, the catering and everything else for the same money. A ring bought before the wedding budget exists is a decision taken with no information, and it is the commonest reason couples find themselves cutting a guest list they did not want to cut.
What can be paid without borrowing. Interest on a ring bought on credit is money spent on nothing at all. If the ring requires finance to reach, the honest position is that the budget is the amount that can be paid outright, and the ring should be chosen to that number.
The approach by budget
Under £1,000, and it buys more than people expect
At this level the published market is genuinely wide. Second-hand diamond rings, lab-grown stones and cluster designs all deliver a real ring with a real stone, and the constraint is on the size of a single natural centre stone rather than on quality.
The mistake at this budget is buying the largest natural stone the money reaches, which means accepting a weak cut. A small bright stone reads as a good ring. A large dull one reads as a compromise, and it does so immediately.
What genuinely does not work below about £300 is a set ring built to last on a hand that works, because at that point the metal and the making have to give somewhere. Plain bands are the exception and are excellent value at any price.
See what a fixed figure reaches across the market
Filtering a large published catalogue by price, rather than by style, is the fastest way to calibrate a budget against reality.

This is where a well cut single stone in a properly made setting becomes straightforward, and where the specification decisions on the buying guide start paying real money. Published prices at this level cover stones from around a fifth of a carat at high grades to half a carat at lower ones, and both are legitimate rings.
The useful discipline here is to set the number first and shop to it, rather than shopping and then setting the number. A figure decided in advance turns a showroom into a comparison exercise. A figure decided in the showroom turns it into a negotiation you are not equipped to win.
Keep something back. Sizing, insurance and the wedding bands are all still to come, and a budget spent entirely on the engagement ring means those get funded from somewhere less comfortable.
Above £3,000, where the returns flatten
Past about three thousand pounds each additional thousand buys less visible difference than the one before it. That is not an argument against spending more, it is a description of where the money goes: into carat weight, into the top of the colour and clarity scales, and into the quality of the making.
Of those three, only the making and the cut reliably show. A buyer at this level who spends the extra on the mount and on cut grade, and holds the stone at the eye-clean threshold, gets a better ring than one who spends the same money climbing the certificate.
Where it stops paying entirely is the round carat weight. Paying the step up to a full carat, for a stone indistinguishable from one a fraction under, is the most expensive aesthetic decision available in the whole category.
What actually makes the difference
- Setting the figure before shopping. A budget decided in a showroom is a budget set by the person selling to you.
- Deciding it against the whole wedding. The ring is one line in a budget that has twenty, and it is the line most often decided in isolation.
- Refusing to borrow for it. Interest on jewellery converts a fixed cost into a larger one with nothing to show for the difference.
- Holding back for what follows. Sizing, insurance and two wedding bands are all still to be paid for, and they are not small.
- Judging by the ring, not the paperwork. The certificate does not go on the hand, and above eye-clean nobody will ever see the difference it records.
Common mistakes
Taking the salary rule seriously in either direction
Some people spend to it and some deliberately spend under it to make a point, and both have let an advertising line set the terms.
Instead: ignore the multiple entirely and set a figure from the wedding budget and what can be paid outright.
Giving a shop a range rather than a figure
A range is heard as a ceiling, so the rings brought out will cluster at the top of it, which is a rational response to the information given.
Instead: state a single number below the true limit, and keep the rest for sizing and insurance.
Buying the ring before the wedding budget exists
The ring is usually the first purchase and the wedding budget is usually settled later, so the largest early commitment is made with the least information.
Instead: agree a rough total for the whole wedding first, even loosely, and allocate the ring within it.
Using finance to reach a size
Interest-free credit makes a larger stone feel reachable, and the payments outlast the moment the size mattered.
Instead: treat the affordable outright figure as the budget, and put the difference into cut and setting.
Comparing your figure with anyone else’s
Reported spends circulate without any statement of what they included, so they compare nothing meaningful and set expectations badly.
Instead: compare published prices for specifications you would actually buy, which is a comparison that means something.
What each level buys, at published prices

Every figure above is a price the supplier publishes openly on its own website, captured on the date shown. Published prices change, they often exclude VAT, delivery and setup, and they are not a quote. Treat them as a guide to the shape of the market, then confirm anything you are relying on directly with the supplier.
Sample: 4 retailers across Northern Ireland, North East England and two UK-wide retailers, captured August 2026.
No figure on this page is an average, and none is offered as one. Published averages for what couples spend circulate widely, usually without a stated method, and they are worth nothing to a person deciding their own budget. What is worth something is knowing that £550 buys a real diamond ring and £2,075 buys a half-carat solitaire at a good grade, both from named sellers on one day.
The history behind the salary rule, from a published account
The campaign that produced the two months’ salary figure is well documented, including the different multiples used in different countries.
