The average engagement ring cost in the US was $4,600 for couples married in 2025, according to The Knot’s 2026 Real Weddings Study of more than 10,000 couples. That is down from $5,200 in The Knot’s 2024 Jewelry and Engagement Study, and the main reason is lab-grown diamonds, which now account for 61% of center stones.
That shift changes what a given budget buys. Below you will find how the average has moved since 2021, what most couples actually spend, how lab-grown and natural stones compare, what moves the price of a ring, and why the salary rule you may have heard was never advice.
Key Takeaways
- The average engagement ring cost $4,600 for US couples married in 2025, per The Knot’s 2026 Real Weddings Study of more than 10,000 couples.
- The average has fallen every year since it was $6,000 in 2021, according to The Knot’s annual surveys.
- A majority of engagement rings now have a lab-grown center stone, a 239% increase since 2020 (The Knot, 2026).
- In 2025, couples spent an average of $4,300 on lab-grown rings and $7,000 on natural-diamond rings (The Knot, reported by Rapaport).
- In The Knot’s 2024 study, 64% spent less than $6,000 and a third spent less than $3,000.
The Average Engagement Ring Cost in the US
There is one national figure worth using, and it comes from The Knot’s annual surveys of real couples.
The Latest Figure
The Knot 2026 Real Weddings Study, released in February 2026 and covering couples married in 2025, is the newest national figure.
The same study found that nearly 9 in 10 proposers had a ring in hand when they asked, so the ring is still close to universal even as what couples pay for it changes.
If you have seen a different number, it is probably an older one. The Knot’s 2024 Jewelry and Engagement Study put the average at $5,200, and many pages still quote that 2024 figure as if it were current.
How the Average Has Changed Since 2021
The Knot’s annual surveys show the average falling every year for five years running.
| Year | Average engagement ring cost | Source |
|---|---|---|
| 2021 | $6,000 | The Knot annual survey |
| 2022 | $5,800 | The Knot annual survey |
| 2023 | $5,500 | The Knot annual survey |
| 2024 | $5,200 | The Knot 2024 Jewelry & Engagement Study |
| 2025 | $4,600 | The Knot 2026 Real Weddings Study (couples married in 2025) |
The fall lines up with the rise of lab-grown center stones, covered further down. JCK quotes The Knot describing that shift as “driven by economic pragmatism and evolving values,” and says it has led to larger average carat sizes and lower average costs.
Who Was Surveyed
The Real Weddings Study is a survey of more than 10,000 US couples who married in 2025, run by The Knot Worldwide.
In plain terms, it measures what couples who actually got married reported paying. It does not track list prices, and it does not ask what a jeweler thinks you should spend. That is what makes it a useful national benchmark.
Retailers also publish statistics from their own sales. Those numbers can be interesting, but they describe that retailer’s customers, not the country as a whole.
What Most Couples Actually Spend
An average is one number. When you set a budget, the spread around it matters more.
Average vs. Typical Spend
A few expensive rings pull an average up, so most buyers spend less than the headline figure suggests. The spread from The Knot’s surveys shows how uneven it is.
In The Knot’s 2024 Jewelry and Engagement Study, 64% of couples spent less than $6,000 and 33% spent less than $3,000.
At the top end of the same 2024 study, 8% spent between $10,000 and $14,999 and 5% spent more than $15,000.
Put together, those shares describe a market where most spending sits in the lower part of the range and a thin tail of large purchases lifts the mean. If your budget lands below the national average, you are in the majority, not the exception.
Regional Differences
The average engagement ring cost in the USA also shifts by region, and The Knot’s regional breakdown comes from an older survey.
The Knot 2023 Real Weddings Study found that couples in the Mid-Atlantic states (Delaware, Maryland, New Jersey, New York, Pennsylvania and Washington, DC) averaged about $6,900.
In the same 2023 study, couples in Virginia and West Virginia averaged $5,300, and the Midwest was the lowest region in the survey at $4,900.
These are 2023 figures, recorded before the national average fell further, so read them as relative gaps between regions rather than current prices where you live.
Lab-Grown vs. Natural Diamonds: The Biggest Cost Driver
The single choice that moves the price most is where the diamond comes from.
Most Center Stones Are Now Lab-Grown
According to The Knot 2026 Real Weddings Study, 61% of engagement rings had a lab-grown center stone, a 239% increase since 2020.
The shift is a choice, not an accident. In the same study, 40% of couples said it was specifically important that their stone be lab-grown.
Price explains much of the appeal. The Knot’s cost guide says lab-grown diamonds can cost 50% to 70% less than natural ones.
Average Spend by Stone Type
Rapaport, reporting The Knot’s figures for couples married in 2025, broke the average down by stone type.
| Center stone | Average engagement ring cost | Average carat weight | Most popular shape | Source |
|---|---|---|---|---|
| Lab-grown diamond, 2025 | $4,300 | 2 carats | Oval | The Knot, reported by Rapaport |
| Natural diamond, 2025 | $7,000 | 1.6 carats | Round | The Knot, reported by Rapaport |
The lab-grown ring is the cheaper of the two on average, even though its stone is the larger one. That gap is the clearest answer to the average engagement ring cost for a natural diamond compared with lab grown.
Bigger Stones for Less Money
Across all rings, Rapaport reported that the average stone grew to 1.9 carats in 2025 from 1.7 carats in 2024, while average spending fell.
For a budget, that means the same money now buys more visible stone than it did a few years ago, mostly through lab-grown. If size matters most to you, stone origin is the first lever to pull; if a natural diamond matters more, expect to trade some size for it.
What Moves the Price of an Engagement Ring
Beyond stone origin, carat weight, the quality grades, shape and setting each push the cost up or down.
| Factor | Pushes the cost up | Keeps the cost down | Source |
|---|---|---|---|
| Stone origin | Natural diamond | Lab-grown diamond, moissanite or a colored gem | The Knot |
| Carat weight | Reaching a whole or quarter carat mark | Buying just under those marks | The Knot; GIA |
| Cut | An excellent cut (usually worth it) | Rarely a good place to save | The Knot |
| Color | Colorless grades D to F | Near-colorless, especially set in yellow gold | The Knot |
| Shape | Round brilliant | Oval, princess, radiant, cushion or heart (less per carat) | GIA |
| Setting | More metal (bezel) or many small diamonds | A simple band | Blue Nile; The Knot |
Carat Weight
Carat measures weight, not size: GIA defines a metric carat as 200 milligrams. If two diamonds match in color, clarity and cut, GIA says the heavier one is rarer and its price will likely be higher, although a diamond’s value reflects all 4Cs, not carat weight alone.
The Knot adds that prices rise sharply at every quarter carat once a stone passes one carat, so a 1.8-carat diamond costs significantly less than a 2-carat one. Buying just under those marks, which The Knot calls buying shy, can save a lot of money.
The Knot’s 2025 cost guide puts a one-carat natural diamond anywhere from $2,000 to $16,000 depending on its 4Cs.
That spread is why no dated survey offers a single average engagement ring cost per carat. The grades move the price as much as the weight does, so a per-carat figure without them tells you very little.
Cut, Color and Clarity
The Knot calls cut usually the most important of the 4Cs, because it affects the diamond’s symmetry and sparkle. That makes it the grade most worth paying for.
Color is where you can be flexible. D, E and F grades are considered colorless and carry greater value, but The Knot notes that hints of color are difficult to detect with an untrained eye, especially in yellow gold settings.
Clarity sits alongside cut and color on the grading report. Weigh it against the other two rather than paying for any single top grade in isolation.
Diamond Shape
GIA’s guide to diamond shapes says ovals are typically more affordable than round brilliants of the same carat weight, and that princess, radiant, cushion and heart shapes cost less per carat than rounds.
Round is still the classic choice, so choosing another outline is one of the easier ways to keep the stone the size you want. For a side-by-side look at each outline, see engagement ring shapes compared.
Setting and Metal
Blue Nile notes that bezel settings use more metal than other designs, so they can be more expensive in some cases. Our guide to what a bezel setting is covers how it holds the stone and who it suits.
The band matters too. James Allen’s chief marketing officer, quoted by The Knot, frames it as a choice between a simple band that will be cheaper and one with many smaller diamonds that takes more of the budget.
On metal, The Knot’s 2026 study, as quoted by JCK, found that 39% of couples chose yellow gold, up 140% over the past five years.
The Three-Month Salary Rule Is Marketing
The most searched rule of thumb has no basis in what couples actually spend.
Where the Rule Came From
The Knot traces the three month salary rule to a De Beers advertising campaign that told buyers to spend one month of their salary on a diamond engagement ring. Over time the idea grew to three months, and The Knot’s verdict is blunt: “it’s just marketing.”
Treat any engagement ring cost rule of thumb, whether it says one month, two or three, as a sales message rather than guidance. None of the survey data in this guide ties what couples spend to what they earn.
Setting a Budget That Fits You
Start from your finances, not a formula. Borrowing for a ring is common: The Knot’s 2024 study found that one in three proposers who buy new rings take on some kind of debt, while about one in four used savings.
Decide what you can pay without new debt and without touching an emergency fund, then choose the stone. If size matters most, lab-grown stretches that number further. If origin matters most, plan for a smaller natural stone. Once the number is fixed, the table below shows where it tends to go furthest.
Where Should Your Budget Go?
Match your situation to what the survey data and grading guides point to.
| Your situation | What the data points to | Why |
|---|---|---|
| Budget under $3,000 | A lab-grown or colored center stone | A third of couples spent less than $3,000 (The Knot 2024) |
| You want the biggest look for the money | A lab-grown oval or another elongated shape | Lab-grown costs less, and elongated shapes look larger per carat |
| You want a natural diamond | Buy just under a whole carat and prioritize cut | Prices jump at whole and quarter carats |
| You would need to borrow | Save first or lower the target | One in three proposers who buy new take on debt (The Knot 2024) |
| Your partner has a clear style | Shop together or ask directly | Nearly four in five people proposed to were involved in choosing |
| You work with your hands | A protective setting and a separate work band | Smooth settings snag less; a work band spares the ring |
On that last row, GIA notes that the smooth edges of a bezel are less likely to catch on clothing or gloves, which makes it a practical choice for people who work with their hands, such as nurses, or anyone with an active lifestyle.
Don’t Forget the Wedding Bands
The ring budget often has to cover two wedding bands as well. The surveys above measure engagement rings only, not the average wedding ring cost, so it helps to set one figure for all three rings and split it, rather than finding out later that the bands were never budgeted.
For a partner who works with their hands, a wedding band built for work can sit alongside the dress ring, and the same thinking applies to rings nurses can wear on shift. For anyone with a nickel allergy, start with hypoallergenic metals.
Frequently Asked Questions
How Much Should a Man Spend on an Engagement Ring?
A man should spend what his savings and income can cover without borrowing, not an amount set by a formula. No salary rule stands behind the figures you hear; the three-month version grew out of De Beers advertising. Pick a number your finances support, then choose the stone and setting that fit inside it.
Is $3,000 Too Little for an Engagement Ring?
No, $3,000 is not too little: in The Knot’s 2024 Jewelry and Engagement Study, a third of couples spent less than that on their engagement ring. At that level, a lab-grown or colored center stone and a simple band stretch the money furthest, and a well-cut stone matters more than the top color grade.
Is $5,000 a Good Budget for an Engagement Ring?
Yes, $5,000 is a good budget: it sits slightly above the $4,600 average that The Knot’s 2026 Real Weddings Study found for couples married in 2025. That leaves you a real choice between a larger lab-grown stone and a smaller natural diamond, depending on whether size or origin matters more to you.
Is $10,000 a Lot for an Engagement Ring?
Yes, $10,000 is a lot compared with what most US couples pay: it is more than double the $4,600 average in The Knot’s 2026 Real Weddings Study. In The Knot’s 2024 study, only 8% of couples spent between $10,000 and $14,999. At that level a natural diamond with a strong cut is within reach.
Is $20,000 Too Much for an Engagement Ring?
A $20,000 ring is too much only if it strains your finances, but in The Knot’s 2024 study it is a rare budget: 5% of couples spent more than $15,000. Spending at that level is a personal choice rather than a mistake. The real risk is borrowing for it, so pay from savings if you can.
How Much Should I Spend on an Engagement Ring If I Make $100,000 a Year?
On a 100,000-dollar salary, there is no correct amount to spend, because no income-based rule is backed by what couples pay. A better anchor is The Knot’s 2026 Real Weddings Study average for couples married in 2025, weighed against what you can cover from savings while the wedding and two bands still need funding.
