The average US engagement ring costs $5,200 according to The Knot 2024 Jewelry & Engagement Study. The Knot Real Weddings Study 2026 puts natural diamond rings at about $7,000 and lab-grown rings at about $4,300. Spending skews low: 64% of buyers stay under $6,000 and 33% under $3,000.
Average Engagement Ring Cost: The Numbers
The national average engagement ring cost is $5,200, based on what buyers told The Knot 2024 Jewelry & Engagement Study they paid.
| Benchmark | Average | Source |
|---|---|---|
| National average engagement ring | $5,200 | The Knot 2024 Jewelry & Engagement Study |
| Natural diamond engagement ring | about $7,000 (1.6 ct average center) | The Knot Real Weddings Study 2026, couples married in 2025 |
| Lab-grown diamond engagement ring | about $4,300 (2.0 ct average center) | The Knot Real Weddings Study 2026, couples married in 2025 |
| Average appraised value of insured rings | about $6,504 | BriteCo insurance data, as cited by Washington Diamond |
| Mid-Atlantic (DE, MD, NJ, NY, PA, DC) | about $6,900 | The Knot 2023 Real Weddings Study |
| Midwest | about $4,900 | The Knot 2023 Real Weddings Study |
Different sources quote different figures because they measure different things. A survey records what buyers say they paid at retail, while insurance data records appraised replacement value. BriteCo's average appraised value of insured rings is about $6,504. That is why many answers quote a range of "$5,200 to $6,500" for the same question.
The average spend has fallen three years in a row. The Knot's annual average dropped from $6,000 in 2021 to $5,800 in 2022, $5,500 in 2023 and $5,200 in 2024. Washington Diamond attributes the decline largely to lab-grown diamonds, which let buyers purchase a larger stone for less money.
The Knot Real Weddings Study 2026 splits the average by stone type. Natural diamond rings average about $7,000 with a 1.6 ct average center stone. Lab-grown rings average about $4,300 with a 2.0 ct average center stone.
How Much Couples Actually Spend
Most couples spend less than the average, because a small group of high spenders pulls the number up. The Knot 2024 Jewelry & Engagement Study reports that 33% of buyers spend under $3,000 and 64% spend under $6,000. At the top, 8% spend $10,000 to $14,999 and 5% spend over $15,000. So the average sits above what most buyers actually pay.
Money sources vary widely. One in three proposers who buy a new ring take on some debt, while about one in four pay from savings.
Shopping takes time. The Knot Real Weddings Study 2026 found that 57% of proposers start searching more than six months ahead. On average, proposers visit two retailers and view about 10 rings before deciding. 64% buy in store rather than online.
Timing is tighter than the search. The Knot 2024 study found 60% of proposers buy the ring about two months before the proposal. And the ring is rarely a solo choice: nearly four in five people who were proposed to had some say in selecting or buying it.
Engagement Ring Cost in New Jersey and the Mid-Atlantic
Mid-Atlantic couples spend more than the national average. The Knot 2023 Real Weddings Study reports an average of about $6,900 for the Mid-Atlantic region (Delaware, Maryland, New Jersey, New York, Pennsylvania and DC). Virginia and West Virginia averaged about $5,300. The Midwest (Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, Wisconsin) averaged about $4,900, the lowest region in that survey.
Billig Jewelers is in Marlton, New Jersey, in the Mid-Atlantic region.
What Drives Engagement Ring Prices
The center stone is usually the largest cost in an engagement ring. Washington Diamond estimates it at 70% to 85% of the total price. The 4Cs (cut, color, clarity, carat) set the stone's price, and each C has a point where spending more stops buying visible improvement.
Carat is weight, not size. Prices jump at round weights such as 0.50, 1.00, 1.50 and 2.00 ct. Jewelers call the workaround "buy shy": 0.90 ct instead of 1.00 ct saves money with no visible size difference on the hand. Color is graded D to Z: D-F is colorless, and G-H stones face up white when set and cost less (see our diamond color scale guide). VS2-SI1 clarity stones are often eye-clean, meaning no inclusions are visible without magnification (more in our diamond clarity scale guide). Cut has the biggest effect on brightness, so it is the C not to cut back on. Shape matters too. Oval, pear and marquise stones look larger than a round of the same carat weight. Always ask for a GIA or IGI grading report.
| C | Where the price jumps | Value range many jewelers recommend | What you trade |
|---|---|---|---|
| Carat | at 0.50, 1.00, 1.50, 2.00 ct | just under a round weight (0.90, 1.40, 1.90 ct) | a size difference not visible on the hand |
| Color | D-F colorless | G-H near-colorless | a faint warmth, hard to see once set (less visible in yellow gold) |
| Clarity | Flawless and VVS grades | VS2-SI1, eye-clean | inclusions visible only under 10x magnification |
| Cut | Excellent or Ideal costs more than Very Good | Excellent or Ideal (do not trade down) | nothing worth saving here |
Natural vs Lab-Grown Diamond Ring Cost
A lab-grown diamond ring costs about $4,300 on average versus about $7,000 for a natural diamond ring, according to The Knot Real Weddings Study 2026. Lab-grown buyers chose larger stones (2.0 ct average center vs 1.6 ct) for about 39% less total spend.
Washington Diamond reports that lab-grown diamonds can sell for 70% to 90% less than natural diamonds of identical specifications. The two are the same material: crystalline carbon, graded on the same 4Cs. The difference is origin and rarity, not chemistry.
Resale is where the gap widens. Lab-grown diamonds have little resale value, while natural diamonds keep part of their retail value. If long-term value matters to you, read our comparison of lab-grown vs natural diamonds before deciding. Moissanite and colored gemstones such as sapphire cost less again and suit tighter budgets.
Setting and Metal Costs
The setting adds to the stone price. Metal choice sets the baseline. 14K gold is 58.3% pure gold and the most budget-friendly gold option. 18K gold is 75% pure gold and costs more (our 14K vs 18K gold guide covers the trade-offs). Platinum costs more than white gold because it is rarer and denser. White gold is rhodium-plated and may need replating over time.
Gold prices affect design choices. Vogue, quoting jeweler Olivia Landau, notes that higher gold prices raise the cost of heavier and chunkier settings. A simple solitaire costs less than a halo or pavé setting with many small accent diamonds.
At our Marlton bench, settings are priced consistently for center stones from 1.00 to 3.00 ct. Custom design includes a free 3D CAD rendering within 48 hours, and most custom projects take 2-3 weeks. Our custom engagement ring cost guide walks through the process and timeline.
The Three-Month Salary Rule and How to Set a Budget
The three-month salary rule is advertising, not tradition. It traces to De Beers advertising during the Great Depression in the 1930s, which told buyers to spend one month's salary. The figure later grew to two months and then three. The Knot calls the rule "just marketing," and most couples spend far less: 64% stay under $6,000.
Washington Diamond describes many couples spending about one month's gross income. On a $100,000 salary that works out to about $8,300 - an example of that framework, not a recommendation.
A practical ring budget comes from your own numbers:
- Set the ceiling from savings and monthly expenses, not a salary multiple.
- Decide natural or lab-grown first, since that choice moves the total the most.
- Pick the C to prioritize - cut, because it controls brightness.
- Include the wedding bands, insurance and appraisal in the total.
- Consider a simpler setting now and a center stone upgrade later.
Costs Beyond the Ring: Appraisal, Insurance and Resizing
The purchase price is not the full cost of owning the ring. A written appraisal documents value for insurance. At Billig Jewelers, written appraisals start at $75, prepared by a GIA Graduate Gemologist for a flat fee - never a percentage of value. Most are ready in 2 business days, and we give a free verbal estimate while you wait.
Insurance needs that paperwork. Homeowners' and renters' policies often cover only $1,000 to $1,500 of jewelry unless the ring is scheduled separately, according to our appraisal page. Resizing starts at $75 for a plain gold band, rhodium included. Platinum and stone-set rings start at $125, most finished in 5 business days. White gold rhodium plating starts at $45. Wedding bands belong in the same budget; our engagement ring vs wedding ring guide explains how the two differ.
| Cost item | Billig price | Notes |
|---|---|---|
| Written appraisal | from $75 | flat fee, most ready in 2 business days |
| Ring resizing, plain gold | from $75 | rhodium included, most in 5 business days |
| Ring resizing, platinum or stone-set | from $125 | most in 5 business days |
| Rhodium plating (white gold) | from $45 | restores white color |
| Prong repair | from $45 | free prong check while you wait |
FAQ

Is a $1,000 engagement ring cheap?
A $1,000 ring is below what most buyers spend, but it is not unusual: 33% of buyers spend under $3,000. At that budget, the usual routes are a lab-grown diamond, moissanite or a smaller natural stone in a simple 14K gold setting.
How much should I spend on an engagement ring if I make $100,000 a year?
No rule ties the ring to your salary; the salary multiple is De Beers marketing. The one-month-of-gross-income framework works out to about $8,300 on a $100,000 salary. Set the number from your savings and monthly costs instead.
What is the 3 month rule for an engagement ring?
The three-month rule is a De Beers advertising guideline. The original campaign in the 1930s told buyers to spend one month's salary, and the figure later grew to three months.
How much does an engagement ring cost in New Jersey?
New Jersey falls in the Mid-Atlantic region, where engagement rings averaged about $6,900 in The Knot 2023 Real Weddings Study. That is above The Knot's national averages for the same period ($5,500 in 2023 and $5,200 in 2024).
Why are diamonds so hard to resell?
The retail price includes cutting, setting and retail margins, but a resale buyer pays closer to wholesale. The gap between retail and resale value is widest for lab-grown diamonds, which have little resale value.
How much does it cost to make a ring with your own stone?
The cost is the setting plus the labor to set your stone. At Billig Jewelers, a custom design starts with a free 3D CAD rendering within 48 hours, so you can approve the design before any work begins.
