Why do buyers want to know the average price of an engagement ring?

Most guys buying an engagement ring will want to find out what the average price is for a diamond ring. After all, who wants to look cheap? On the other hand, many guys prefer not to go too far when it comes to the price of a ring. Consequently, a little insight and a benchmark on cost will help many buyers decide on a suitable budget.

Are big jewellery brands best on price?

Many buyers steer towards well-known, big brand jewellers as their first step when choosing a ring. This is because well known jewellery stores such as H Samuel, Warren James, Ernest Jones, Beaverbrooks and Goldsmiths are household names to most people. Certainly for anyone willing to explore a little further afield, there are more opportunities provided by smaller independent jewellery stores. You will be surprised by the difference available based on the average price of an engagement ring.

How many month’s salary does tradition suggest you spend?

DeBeers created the first rule-of-thumb back in the 1930’s. Their suggestion was to spend one month’s salary on an engagement ring. Rather interestingly, by the 1980’s this suggestion had risen to spending an amount relating to two month’s salary. Later, in Japan, buyers were encouraged to spend a figure based on three months salary. As a result, there has been much confusion for buyers. Should you spend one month’s salary or three month’s salary? This is the DeBeers myth.

What is the average salary in the UK?

The Office of National Statistics puts the average UK salary at £27,271. Subesquently, this would give a net income per month of around £1800.00. Traditionally, buyers could be looking at spending between £1800 (one month’s average salary) and £5400 (three months average salary) depending on which version of tradition you favour!

The average engagement ring price at Serendipity Diamonds

As a result of our own research of 3 years of engagement ring sales, the average price of an engagement ring price at Serendipity Diamonds works out to £1700.00 GBP. This is a fairly typical spend for a solitaire, three stone, or cluster style diamond engagement ring. For many, this is also a realistic budget for a certified diamond engagement ring in a high quality precious metal.

Do chain jewellery stores offer best value?

In our experience, the large multiple jewellery stores do not offer the buyer best value at the average cost of an engagement ring. Compared to bespoke jewellers, off-the-shelf engagement rings tend to be mass produced. In particular, many of the cheaper, lower quality engagement rings are mass produced in the Far East. However, the advantage for the consumer becomes one of availability and purchasing an engagement ring without delay. In contrast, our own engagement rings are created for each client based around specific preferences.

We compared our own £1700 rings to other well-known jewellery stores.

We took 5 jewellery stores, with websites, and compared a classic round brilliant cut solitaire ring. This is what we found basing our research on an average price of around £1700.00

1. Serendipity Diamonds – Best Value

2. Goldsmiths

Two star rating



Goldsmiths average engagement ring price

What engagement ring can you buy for £1700 at Goldsmiths?

During our online search, we discovered a comparable ring design in 18ct White Gold. Set with a 0.25cts diamond of no specified quality or grade the ring came in at £1750.00. Although this was a little more than our average spend, it was the closest we could identify.

3. H. Samuel


H Samuel comparison engagement ring cost

What does £1700 get you for an engagement ring at H Samuel?

18ct White Gold. 0.33cts diamond. I colour I1 clarity. 

Why 3 stars? – Although a smaller diamond, specifications were available despite being hard to find. Interestingly and on a side note, we were unable to identify the laboratory certifying the diamond, stated as GSI.

4. Beaverbrooks


Beaverbrooks engagement ring average price

Next we looked at Beaverbrooks, another of the popular High Street jewellers.

What does £1700 get you for an engagement ring at Beaverbrooks?

Unfortunately we were unable to find a similar diamond engagement ring for our £1700 average cost. Instead we had to climb by another £150.00 for a smaller diamond.

18ct White Gold. 0.28cts. G colour SI1 clarity. No certification specified. 

Why 2 stars? – This year, Beaverbrooks have quite surprisingly fallen behind H Samuel. Most noteworthy in our research, we noticed that they are providing a diamond grading certificate produced by themselves. Buyers typically gain far greater trust from certificates produced by recognised independent laboratories such as GIA. 

5. Ernest Jones

Two star rating

Ernest Jones comparison engagement ring

Again we struggled within the price range. As a result, we had to push the budget up to £1800 to find an equivalent engagement ring comparable to other diamond engagement rings at an average cost.

What does £1750 get you for an engagement ring at Ernest Jones?

For £1799.00 you can get a 2/5 carat (this is 0.40cts for anyone scratching their heads) Another observation, no specified colour or clarity grades were given for the diamond. 

Why only 2 stars? – Very little information again as we noted last year. Unfortunately, for the consumer no information on diamond quality appears on the website page.
