Why Are Lab-Grown Diamonds Becoming More Popular?
Lab-grown diamonds are gaining ground because they offer the same diamond material at a lower price, with a clear origin and independent certification. Shoppers who once chose a smaller natural stone can now often afford a larger or higher-quality one.
Quick Answer
Lab-grown diamonds are becoming more popular mainly because they cost less than comparable natural diamonds while being chemically and visually the same material. Other drivers include a known origin, wider availability of certified stones, and buyers who prefer to spend on size, design, or other priorities. The trade-off is that lab-grown diamonds usually resell for less.
Key Takeaways
- In The Knot's 2026 Real Weddings Study, 61% of engagement rings bought in 2025 had a lab-grown center stone, up 239% since 2020.
- Price is the main driver. Buyers can often choose a larger or higher-grade lab-grown stone for the same budget.
- Lab-grown diamonds are real diamonds. The FTC requires sellers to disclose that a stone is lab-grown.
- Independent certification and a known origin reassure buyers who want documented specifications.
- Resale is the main drawback: lab-grown diamonds generally resell for a lower share of retail than natural ones.
- That figure comes from one large US survey of engagement rings. It does not cover every jewelry category or country.
How Popular Are Lab-Grown Diamonds Right Now?
Lab-grown diamonds are now the majority choice for US engagement ring center stones, according to The Knot Worldwide's 2026 Real Weddings Study, which surveyed 10,474 US couples married in 2025. Trade coverage of the study notes that the share first passed 50% in 2024.

These numbers describ e engagement rings in one survey. They do not show that lab-grown stones make up most of all diamond jewelry sold, and results in other countries may differ.
Why Are More People Choosing Lab-Grown Diamonds?
1. They cost less for the same material
A lab-grown diamond typically costs much less than a natural diamond with similar grades. Growing diamonds on demand avoids mining and long supply chains, and production methods have become more efficient. Because the material is the same, buyers are not giving up hardness or sparkle to get the lower price. The size of the gap varies by stone and changes over time, so check current listings.
2. Budgets stretch further
Lower prices change how people spend. Instead of a smaller natural diamond, a shopper may choose a larger stone, a higher color or clarity grade, or put more of the budget into the setting. The Knot's study reports an average lab-grown center stone of 1.9 carats, and about 40% of respondents said it was important that their stone be lab-grown.
3. The stone is documented
Lab-grown diamonds are commonly sold with reports from laboratories such as IGI, which record the stone's specifications and identify it as laboratory-grown. A report, and often a laser inscription matching it, lets a buyer verify what they are getting.
4. The origin is known
Every lab-grown diamond comes from a known production facility. Some buyers prefer that traceability to the varied sourcing of mined stones. Environmental claims on both sides are contested, though, and the FTC cautions against broad claims like "eco-friendly" without evidence, so specific facts matter more than slogans.
5. Designs and shapes are widely available
With more stones available in more shapes, buyers can pick styles such as hidden halo, bezel, or three stone without paying a premium for a large center diamond. Custom work becomes easier to plan too.
The Reasons at a Glance
| Driver | What it means for buyers | Caveat |
|---|---|---|
| Lower price | More size or quality per dollar | Prices change over time |
| Same material | Same hardness and appearance as natural | Origin is still disclosed and priced differently |
| Certification | Independent report on the stone | Reporting styles differ by laboratory |
| Known origin | Traceable production | Environmental impact depends on the facility |
| Design freedom | Bigger stones and more styles | Setting quality still matters |
What Growing Popularity Does Not Change
Popularity does not make lab-grown diamonds an investment. They generally resell for a lower share of retail than natural diamonds, and some jewelers do not offer buy-back. Natural diamonds usually resell below what you paid as well, so neither should be bought mainly for resale.
It also does not change the rules on wording. The FTC's Jewelry Guides treat lab-grown diamonds as diamonds, and sellers must clearly say a stone is lab-grown. If a listing calls a stone simply "diamond" or "natural," ask for clarification.
What Should You Check Before Buying a Lab-Grown Diamond?
- The report. Confirm the laboratory, that the stone is stated as laboratory-grown, and that the report number matches the stone.
- The cut. Cut drives how bright the stone looks, so compare it before size.
- The terms. Read the return policy and warranty, and get any trade-in or upgrade promise in writing.
- The setting. Check prongs, stone security, and band thickness, especially on larger stones.

Frequently Asked Questions
Why are lab-grown diamonds so popular?
Mainly because they offer the same diamond material for a lower price, so buyers can get a larger or higher-grade stone for their budget. Certification and a known origin add to the appeal.
Are lab-grown diamonds more popular than natural diamonds?
For US engagement rings, yes, in one major survey: 61% of rings bought in 2025 had lab-grown center stones. That applies to engagement rings in that survey, not to all diamond jewelry worldwide.
Are lab-grown diamonds real?
Yes. They are diamonds with essentially the same chemical composition and physical properties as natural diamonds. The FTC requires sellers to clearly disclose that a stone is lab-grown.
Are lab-grown diamonds a good investment?
Not usually. They tend to resell for a lower share of retail than natural diamonds, and some jewelers will not buy them back. They suit buyers who want to wear a diamond, not resell it.
Are lab-grown diamonds better for the environment?
It depends on the facility. Mining disturbs land, while growing diamonds uses substantial electricity, and studies reach different conclusions. Ask for specific evidence, not general "eco-friendly" claims.
Do lab-grown diamonds come with certificates?
Many do. Laboratories such as IGI issue reports that identify the stone as laboratory-grown and record its grades. Some stones have a laser inscription that matches the report number.
Will lab-grown diamond prices keep falling?
No one can say for certain. Prices have moved a lot in recent years, and analysts disagree about whether they have stabilized. Compare current listings and avoid buying based on a prediction.
Do lab-grown diamonds look different from natural ones?
No. They match natural diamonds in hardness and brilliance, and separating them takes laboratory instruments. Cut quality has a much larger effect on appearance than origin.
Final Thoughts
Lab-grown diamonds are gaining ground because the material is the same and the price and paperwork are clearer, not because of a passing trend. They fit buyers who value size, design, and documented specifications, and they fit poorly for anyone counting on resale. Browse the rings collection to compare styles, or read the store FAQ.
