Key Takeaways:
- Lab Diamond Formation: Lab diamonds grow using HPHT or CVD methods that recreate natural diamond-forming conditions in a controlled setting. A stone that would take the earth many years to form can be grown in a matter of weeks to a few months.
- Shared Composition, Different Origin: Lab and natural diamonds are chemically identical and graded by the same standards. A jeweler's loupe alone cannot tell the two apart; only specialized gemological equipment can trace a stone's origin.
- Price Reflects Rarity, Not Quality: Lab diamonds often carry more accessible pricing since they skip the extraction process. That can free up your budget for a larger stone or a higher clarity grade, and our team is glad to walk you through what fits your priorities.
Shopping for an engagement ring or a piece of fine jewelry lately, you have likely run into the term more than once, often next to a price tag that seems too good to be true. So what is a lab diamond, and how does it stack up against the natural stones your grandmother might have worn? We hear this question from customers walking through our doors nearly every week.
At Jewelry Authority, we’ve proudly spent more than 60 years helping people understand exactly what they are buying, from one-of-a-kind estate pieces with decades of history to lab grown diamonds built for a modern love story. Across our two Greensboro showroom locations, our industry-leading gemological technology lets us speak to lab diamonds with the same honesty and precision we bring to grading a century-old heirloom.
In this article, we walk you through what a lab diamond is, how it is made, how it compares to a natural diamond, and what it is worth knowing before you shop.
How Are Lab Diamonds Made?
A lab diamond starts the same way a natural one does, with pure carbon, but the process that shapes it happens in a controlled setting rather than deep within the earth. Using one of two methods, High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD), scientists recreate the conditions needed for carbon atoms to bond into a diamond crystal structure. From there, HPHT applies intense heat and pressure to a small diamond seed, and CVD grows a diamond layer by layer inside a chamber filled with carbon-rich gas.
This process results in a stone with the same crystal structure, hardness, and brilliance as a natural diamond, simply grown on a different timeline. Where the earth takes over a billion years to form a diamond, this process takes weeks to a few months. When you visit either of our Greensboro showrooms, our team is happy to walk you through how each stone came to be, whether it was grown in a lab or found in the earth generations ago.
What Is A Lab Created Diamond, Really? Comparing Lab Grown To Natural Diamonds
Answering what is a lab created diamond really comes down to comparison, since the best way to appreciate any stone is to see how it measures up against its counterpart. Natural and lab grown diamonds share the same chemical makeup but differ in origin, rarity, and the story behind how each one came to exist. Here's how the two compare.
Chemical And Physical Composition
A lab created diamond is chemically identical to a natural diamond, made of pure crystallized carbon with the same hardness and refractive brilliance. The difference lies entirely in where and how the crystal formed, not in what it is made of. Both are, in every sense, real diamonds.
Rarity And Origin
Natural diamonds carry the weight of geological history, formed over more than a billion years beneath the earth's surface, which is part of what makes each one so personal to discover. Lab diamonds are grown intentionally, offering a different kind of story rooted in modern craftsmanship and precision.
Grading And Certification
Natural and lab diamonds are graded using the same criteria: cut, color, clarity, and carat weight. Independent gemological labs certify each stone accordingly, so when you shop with us, every diamond, regardless of origin, gets evaluated against the same rigorous standard, and our team can walk you through the certificate line by line.
What Is A Lab Grown Diamond Worth? Value, Price, And Why It Matters When You're Shopping
Price draws many people to lab diamonds first, but the reason behind that price gap matters just as much as the number itself. Here's what to weigh as you shop.
Why Lab Diamonds Are Priced Differently
Lab diamonds typically cost less than natural diamonds of comparable size and quality, largely because producing them skips the geological rarity and extraction process behind a natural stone. That gap gives you room to choose a larger stone or a higher clarity grade within the same budget, without giving up brilliance or durability.
What To Look For When Shopping
Certification matters just as much with lab diamonds as it does with natural ones. When you browse our Lab Diamond collection, you’ll find pieces backed by proper grading, so you can shop with confidence and clarity about what you’re bringing home.
Making The Choice That Feels Right For You
No universally correct answer exists between lab grown and natural, only what feels right for you. Modern precision draws some buyers toward a lab diamond, and the history carried in a natural stone draws others toward that instead. Either way, we walk through your options with you fully before you decide.
Final Thoughts
Choosing between a lab created stone and a natural one isn't about picking a right answer, since both carry real beauty, real durability, and real meaning depending on what resonates with you. A clear picture of how each type of diamond comes to be, how it's graded, and what sets the pricing apart is what lets you confidently decide, whether modern craftsmanship or the quiet history behind an older stone draws you in.
Our team spends every day immersed in this world, from grading loose stones to sourcing one-of-a-kind estate pieces, and we bring that same depth of experience to every conversation about lab diamonds. Whether you are buying your first engagement ring or considering a piece from your own collection, we would love to help.

Frequently Asked Questions About What Is A Lab Diamond
Is a lab diamond a real diamond?
Yes. These diamonds share the same composition, hardness, and brilliance as a natural diamond, just formed differently.
Can you tell the difference between a lab diamond and a natural diamond just by looking at it?
Not with the naked eye. It takes specialized gemological equipment, which our Greensboro team uses every day.
Do lab diamonds hold their value the same way natural diamonds do?
Value depends on several factors, so we recommend booking a consultation with our team for honest, personalized guidance.
Are lab diamonds a good choice for an engagement ring?
