The Complete Guide to Lab Grown Diamonds: Everything You Need to Know Before You Buy
For generations, diamonds have represented love, commitment, and life's most meaningful milestones. Today, modern technology has introduced a remarkable alternative that is transforming the jewelry industry: lab grown diamonds.
As more couples research engagement rings online, one question appears again and again:
Are lab grown diamonds real?
The answer is simple:
Yes—they are 100% real diamonds.
Lab grown diamonds possess the exact same chemical composition, crystal structure, hardness, brilliance, and fire as diamonds formed naturally beneath the Earth's surface. Even experienced jewelers cannot distinguish a lab grown diamond from a mined diamond without specialized gemological equipment.
At Angelucci Jewelry, we've helped thousands of clients navigate one of the most important purchases of their lives. Whether you're shopping for your first engagement ring or upgrading an heirloom piece, understanding how lab created diamonds compare to natural diamonds is essential to making a confident, informed decision.

What Are Lab Grown Diamonds?
A lab grown diamond (also called a lab created diamond, laboratory grown diamond, or man-made diamond) is a genuine diamond created inside a highly controlled laboratory that replicates the natural conditions under which diamonds form within the Earth.
Rather than taking billions of years to develop underground, these diamonds are grown over several weeks using advanced technology.
The result is extraordinary.
Every lab grown diamond consists entirely of carbon atoms arranged in the identical crystalline structure found in mined diamonds.
That means lab diamonds have the same:
-
Hardness (10 on the Mohs scale)
-
Fire
-
Brilliance
-
Scintillation
-
Optical properties
-
Thermal conductivity
-
Durability
In other words, they are not "diamond simulants." They are genuine diamonds in every scientific sense.
Are Lab Diamonds Real Diamonds?
This is perhaps the most searched question online.
Yes.
Lab diamonds are real diamonds.
Organizations including the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) classify laboratory-grown diamonds as diamonds because they possess the exact same physical and chemical characteristics as mined diamonds.
The only meaningful difference lies in their origin.
Natural diamonds formed deep inside the Earth over billions of years.
Lab grown diamonds formed inside a laboratory over several weeks.
Once they are fully grown, there is no visible difference between them.
Even professional diamond testers recognize lab grown diamonds as genuine diamonds because they exhibit the same thermal conductivity as natural diamonds.
So if you've wondered:
-
Are lab grown diamonds real?
-
Are lab diamonds fake?
-
Do lab diamonds test as real?
The answer is straightforward:
Yes—they are real diamonds, and yes, they test as real.
Why More Couples Are Choosing Lab Grown Engagement Rings
Consumer preferences have changed dramatically over the past decade.
Today's buyers are increasingly looking for:
-
Larger diamonds
-
Better color grades
-
Higher clarity
-
Exceptional value
-
Ethical sourcing
-
Modern craftsmanship
Lab grown diamonds allow couples to maximize beauty without sacrificing quality.
Rather than choosing between size and quality, many buyers can enjoy both.
For example, a budget that might purchase a one-carat natural diamond may instead allow for a significantly larger lab grown diamond with superior color and clarity.
This has made lab grown engagement rings one of the fastest-growing categories in fine jewelry.
At Angelucci Jewelry, our clients appreciate the flexibility that lab grown diamonds provide. Whether selecting a timeless solitaire or designing a completely custom engagement ring, lab diamonds make exceptional craftsmanship more accessible while preserving the beauty and symbolism that define a lifelong commitment.
If you're looking for elegant settings designed to highlight the brilliance of a lab grown diamond, explore our handcrafted collection of solitaire engagement rings: https://angeluccijewelry.com/collections/solitaire-pear-marquise-oval-and-emerald-shape-engagement-rings?utm_source=chatgpt.com
Each design is created to emphasize the diamond itself—allowing its fire, brilliance, and proportions to take center stage.
The Evolution of Diamond Buying
Buying an engagement ring today looks very different than it did twenty years ago.
Modern consumers spend weeks—or even months—researching online before making a purchase. They compare diamond grading reports, study cut quality, watch educational videos, and ask AI-powered search engines questions like:
-
Are lab grown diamonds worth buying?
-
Lab grown diamond vs natural diamond
-
HPHT vs CVD diamonds
-
IGI certified lab diamonds
-
GIA lab grown diamonds
-
Lab grown diamond vs moissanite
-
Lab grown diamond vs cubic zirconia
The abundance of information can feel overwhelming, but it also empowers buyers to make educated decisions based on science, craftsmanship, and personal values rather than marketing myths.
Throughout this guide, we'll answer each of these questions in detail—from how lab diamonds are created to how they're graded, certified, compared with natural diamonds, and ultimately chosen for an engagement ring you'll treasure for a lifetime.
Next: In Section 2, we'll take a deeper look at the differences between lab grown diamonds and natural diamonds, dispelling common misconceptions and helping you determine which option is right for your lifestyle, values, and budget.
Section 2
Lab Grown Diamonds vs. Natural Diamonds: Understanding the Real Differences
Approx. 600 words
One of the most common questions we hear from clients at Angelucci Jewelry is:
"Should I choose a lab grown diamond or a natural diamond?"
The truth is, there isn't a universally "better" choice. The right diamond depends on your priorities, values, budget, and the story you want your jewelry to tell. Both lab grown and natural diamonds are genuine diamonds with exceptional beauty. Understanding the differences allows you to make a decision with confidence.
If you're beginning your search for the perfect engagement ring, explore our handcrafted collection of solitaire pear, marquise, oval, and emerald-cut engagement rings, designed to showcase both natural and lab grown diamonds with timeless elegance:
Natural vs. Lab Grown Diamonds
The most significant difference between a natural diamond and a lab grown diamond is how it was created.
A natural diamond forms approximately 100 to 150 miles beneath the Earth's surface under extreme heat and pressure over billions of years. Through volcanic eruptions, these diamonds eventually make their way closer to the Earth's surface, where they are mined, cut, polished, and transformed into fine jewelry.
A lab grown diamond is produced in a laboratory using advanced technology that recreates these same natural conditions. Instead of taking billions of years, the crystal grows in a matter of weeks before it is cut and polished by expert diamond cutters.
Once complete, both diamonds share identical:
-
Chemical composition (pure crystallized carbon)
-
Crystal structure
-
Hardness (10 on the Mohs scale)
-
Fire and brilliance
-
Optical performance
-
Durability
-
Thermal conductivity
Even trained gemologists cannot determine whether a diamond is natural or lab grown by sight alone. Specialized equipment is required to identify its origin.
Appearance: Can You Tell the Difference?
One of the biggest misconceptions surrounding lab created diamonds is that they somehow "look different."
They don't.
A properly cut lab grown diamond displays the same breathtaking sparkle, brilliance, and fire as a mined diamond. The beauty of any diamond is determined primarily by its cut quality—not whether it was grown in the Earth or in a laboratory.
An Excellent or Ideal-cut lab grown diamond will often appear more brilliant than a poorly cut natural diamond.
This is why choosing a trusted jeweler who prioritizes cut quality is just as important as selecting the diamond itself.
At Angelucci Jewelry, we carefully curate diamonds that meet strict standards for brilliance, symmetry, and craftsmanship, ensuring every engagement ring reflects the highest level of quality.
Diamond Grading Is the Same
Another common misconception is that lab diamonds are graded differently.
In reality, both natural and lab grown diamonds are evaluated using the internationally recognized Four Cs:
Cut
The cut determines how effectively a diamond reflects light. Excellent proportions produce maximum brilliance, sparkle, and fire.
Color
Diamonds are graded from D (colorless) through Z (noticeable yellow or brown tint). Many clients choose D–F for an icy white appearance or G–H for outstanding value while maintaining a near-colorless look.
Clarity
Clarity measures the number and visibility of natural internal characteristics called inclusions and external blemishes. Higher clarity grades generally indicate fewer visible imperfections.
Carat Weight
Carat refers to a diamond's weight—not its physical dimensions. Two diamonds with the same carat weight can appear different in size depending on their cut proportions.
Whether a diamond is natural or lab grown, these grading standards remain exactly the same.
Certification Matters
Whenever you purchase a significant diamond, certification is essential.
Independent grading laboratories verify a diamond's characteristics and provide confidence in its quality.
For lab grown diamonds, the two most respected organizations are:
-
IGI (International Gemological Institute) — the world's leading laboratory for grading lab grown diamonds.
-
GIA (Gemological Institute of America) — one of the most recognized names in diamond grading, also offering grading reports for laboratory-grown diamonds.
An IGI certified lab diamond or GIA lab grown diamond gives buyers assurance that the diamond has been independently evaluated for its cut, color, clarity, carat weight, and growth origin.
At Angelucci Jewelry, we believe transparency builds trust. We proudly offer certified diamonds and guide our clients through every aspect of the grading report so they fully understand the quality of the diamond they are purchasing.
Value and Buying Power
One of the most compelling advantages of lab grown diamonds is the exceptional value they offer.
Because they can be grown in controlled laboratory environments rather than mined from the Earth, lab grown diamonds are generally available at significantly lower prices than natural diamonds of equivalent quality.
This often allows buyers to:
-
Choose a larger center stone.
-
Upgrade to a higher color grade.
-
Select a better clarity grade.
-
Invest in a more elaborate custom setting.
-
Stay comfortably within their planned budget.
For many couples, this means purchasing a diamond that would have been financially out of reach just a few years ago.
Whether you envision a classic solitaire, a sophisticated hidden halo, or a fully bespoke design, lab grown diamonds provide extraordinary flexibility without compromising beauty.

Which Diamond Is Right for You?
Choosing between a natural diamond and a lab grown diamond isn't about determining which is "better." It's about choosing the option that aligns with your personal preferences.
If you value geological rarity and the history of a diamond formed over billions of years, a natural diamond may be the perfect fit.
If you prioritize exceptional size, quality, value, modern innovation, and flexibility within your budget, a lab grown diamond may be exactly what you're looking for.
Both are authentic diamonds. Both symbolize lasting love. Both can become treasured heirlooms for generations when selected thoughtfully and crafted with care.
In Section 3, we'll explore how lab grown diamonds are actually created, taking an inside look at the two revolutionary technologies—HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition)—that produce these remarkable gemstones, and what every buyer should know before making a purchase.
Section 3
How Lab Grown Diamonds Are Made: HPHT vs. CVD Explained
Approx. 650 words
One of the most fascinating aspects of lab grown diamonds is the technology behind them. While many people know that these diamonds are created in a laboratory rather than mined from the Earth, fewer understand how they are actually formed.
The answer lies in two groundbreaking manufacturing methods:
-
HPHT (High Pressure High Temperature)
-
CVD (Chemical Vapor Deposition)
Both processes produce real diamonds with the same physical, chemical, and optical properties as natural diamonds. Neither method creates a "fake" diamond, and both are recognized by leading gemological laboratories around the world.
If you're considering a lab grown engagement ring, understanding these two processes can help you make a more informed purchase.
When paired with a timeless setting, a beautifully cut lab grown diamond becomes the centerpiece of a ring designed to last a lifetime. Explore Angelucci Jewelry's handcrafted collection of solitaire pear, marquise, oval, and emerald-cut engagement rings to see how exceptional craftsmanship brings every diamond to life:
The Science Behind Lab Grown Diamonds
Every diamond—whether mined from the Earth or grown in a laboratory—is made from one element:
Carbon.
What makes diamonds unique is not their composition but the way carbon atoms bond together under immense pressure and heat to form an incredibly strong crystal structure.
Natural diamonds form deep beneath the Earth's surface over billions of years.
Scientists have learned how to recreate these same conditions inside highly controlled laboratory environments, dramatically accelerating the process without changing the final product.
The result is a genuine diamond that is chemically, physically, and optically identical to one found in nature.
HPHT Diamonds (High Pressure High Temperature)
HPHT technology was the first commercially successful method used to grow gem-quality diamonds.
The process closely mimics the natural conditions found deep inside the Earth.
Here's how it works:
A tiny slice of diamond known as a diamond seed is placed into a growth chamber along with purified carbon.
The chamber generates extraordinary conditions:
-
Temperatures exceeding 2,500°F (1,370°C)
-
Pressure approaching 1.5 million pounds per square inch
Under these conditions, the carbon melts and crystallizes around the seed.
Over several weeks, the crystal gradually grows into a rough diamond suitable for cutting and polishing.
Because HPHT replicates Earth's natural diamond-forming environment so closely, it produces exceptionally durable, high-quality diamonds.
Many colorless and near-colorless laboratory diamonds available today are created using HPHT technology.
CVD Diamonds (Chemical Vapor Deposition)
The second major production method is Chemical Vapor Deposition (CVD).
Unlike HPHT, CVD grows diamonds layer by layer.
The process begins with another small diamond seed placed inside a sealed vacuum chamber.
Carbon-rich gases—typically methane mixed with hydrogen—are introduced into the chamber.
Powerful microwaves heat the gases into plasma.
As the gases break apart, pure carbon atoms separate and slowly attach themselves to the diamond seed.
Over time, these microscopic layers build upon one another until a complete diamond crystal forms.
Once growth is complete, many CVD diamonds undergo additional HPHT treatment to optimize their color and remove trace defects, resulting in exceptionally bright, colorless diamonds.
Today, CVD has become one of the most popular methods for producing premium-quality lab grown diamonds because it allows remarkable precision and consistency.
HPHT vs. CVD: Is One Better?
One of the most common questions buyers ask is:
"Which is better—HPHT or CVD?"
The simple answer is:
Neither is inherently better.
Both methods create genuine diamonds.
Both can produce diamonds with outstanding:
-
Brilliance
-
Fire
-
Hardness
-
Durability
-
Optical performance
What matters far more than the growth process is the individual quality of the finished diamond.
When purchasing a diamond, experienced jewelers focus on:
-
Cut quality
-
Color
-
Clarity
-
Symmetry
-
Polish
-
Overall light performance
A beautifully cut CVD diamond can outperform a poorly cut HPHT diamond—and vice versa.
This is why buying from a trusted jeweler who carefully evaluates every diamond is more important than selecting one manufacturing process over another.
At Angelucci Jewelry, we select diamonds based on their overall beauty and performance, ensuring that every stone meets our uncompromising standards for brilliance and craftsmanship.
Are HPHT and CVD Diamonds Certified?
Yes.
Just like natural diamonds, laboratory-grown diamonds are independently graded by respected gemological laboratories.
An IGI Certified Lab Diamond or GIA Lab Grown Diamond receives a grading report detailing:
-
Carat weight
-
Cut grade
-
Color grade
-
Clarity grade
-
Polish
-
Symmetry
-
Measurements
-
Growth method (HPHT or CVD)
-
Laser inscription (when applicable)
These reports provide complete transparency and give buyers confidence in exactly what they are purchasing.
Always ask for a grading certificate when buying a significant diamond, regardless of whether it is natural or laboratory grown.
Do Lab Grown Diamonds Test as Real?
Absolutely.
This is another question buyers frequently ask.
Professional diamond testers identify diamonds based primarily on thermal conductivity.
Since lab grown diamonds possess the exact same thermal properties as natural diamonds, they test positive as real diamonds.
This distinguishes them from common diamond simulants such as cubic zirconia or moissanite.
We'll explore those differences in greater detail in the next section.
Precision Meets Timeless Craftsmanship
While advanced technology creates the diamond itself, craftsmanship transforms it into a meaningful piece of jewelry.
The setting, proportions, finishing, and attention to detail are what elevate an engagement ring from beautiful to unforgettable.
At Angelucci Jewelry, every engagement ring is handcrafted with precision to maximize the beauty of each center stone.

Frequently Asked Questions
Are Lab Grown Diamonds Real?
Yes.
This is the most common question—and the easiest to answer.
A lab grown diamond is a real diamond made from crystallized carbon. It has the same chemical composition, crystal structure, hardness, brilliance, and durability as a mined diamond.
The only difference is where it formed.
Natural diamonds formed underground over billions of years.
Lab grown diamonds formed in a controlled laboratory over several weeks using advanced technology.
Do Lab Diamonds Test as Real?
Absolutely.
Professional diamond testers identify diamonds through their thermal conductivity.
Since laboratory-grown diamonds have the same thermal properties as natural diamonds, they test as genuine diamonds using standard diamond testers.
This is one of the reasons they are recognized by respected grading laboratories such as IGI and GIA.
Are Lab Grown Diamonds Worth Buying?
For many buyers, the answer is yes.
Lab grown diamonds offer exceptional beauty, outstanding quality, and remarkable value.
Many couples appreciate the opportunity to purchase:
-
A larger center diamond
-
Higher color grades

—all while staying comfortably within their planned budget.
Ultimately, the "best" diamond is the one that aligns with your priorities, whether that's rarity, value, size, craftsmanship, or personal preference.
Will a Lab Grown Diamond Last Forever?
Yes.
Diamonds are the hardest naturally occurring material known, ranking 10 on the Mohs Hardness Scale.
Because laboratory-grown diamonds have the exact same crystal structure as natural diamonds, they possess the same durability and are suitable for everyday wear.
With proper care, a lab grown engagement ring can be enjoyed for generations.
Do Lab Grown Diamonds Lose Their Sparkle?
No.
A diamond's sparkle comes from its cut quality—not where it originated.
A well-cut lab grown diamond will maintain its brilliance indefinitely.
Regular professional cleaning simply removes oils and everyday residue that can temporarily reduce light performance.
Can Lab Grown Diamonds Become Family Heirlooms?
Absolutely.
The emotional significance of a diamond comes from the memories and relationships it represents—not where it was formed.
The engagement ring you exchange today may become the treasured heirloom passed to your children and grandchildren tomorrow.
At Angelucci Jewelry, we believe every piece tells a story, and that story only becomes more meaningful with each generation.
Lab Grown Diamond vs. Moissanite
Many buyers compare lab grown diamonds with moissanite.
Although both are beautiful gemstones, they are not the same material.
Lab Grown Diamond
-
Genuine diamond
-
Pure crystallized carbon
-
Hardness of 10
-
Traditional diamond brilliance
-
Tests as a real diamond
-
Certified by diamond grading laboratories
Moissanite
-
Silicon carbide
-
Hardness of approximately 9.25
-
Produces more rainbow-colored flashes
-
Does not have the same crystal structure
-
Does not test as a natural diamond on advanced identification equipment
Moissanite offers excellent value and durability, but it is a diamond alternative—not a diamond.
Lab Grown Diamond vs. Cubic Zirconia
Cubic zirconia (CZ) is another popular diamond substitute.
Unlike lab grown diamonds, cubic zirconia is a synthetic crystal made from zirconium dioxide.
Compared with diamonds, CZ:
-
Is significantly softer
-
Scratches more easily
-
Loses brilliance over time
-
Is noticeably heavier
-
Does not possess the same optical performance
-
Does not test as a genuine diamond
For buyers seeking the authentic beauty and durability of a diamond, laboratory-grown diamonds are in an entirely different category.
