Fab Diamond (Lab Grown Diamonds)
What Is a Fab Diamond?
A Fab Diamond is a real diamond created in a laboratory using advanced technology that reproduces the natural diamond formation process. Instead of forming deep within the Earth over billions of years, a fab diamond grows in a controlled environment where carbon atoms crystallize into the same atomic structure found in mined diamonds.
Fab diamonds are composed of pure carbon and share the same physical, chemical, and optical properties as natural diamonds. They are not simulants or imitations. A fab diamond is a genuine diamond, distinguished only by how it is created.
The term “Fab Diamond” comes from the word “fabricated” and is commonly used as an informal way to describe lab grown diamonds. In professional and gemological contexts, the standard term is lab grown diamond, but both expressions refer to the same type of stone.
Fab Diamond Meaning
Fab Diamond refers to a diamond that has been fabricated in a laboratory rather than extracted from the earth. This fabrication process allows scientists to recreate the exact conditions under which diamonds naturally form, producing a crystal that is structurally identical to a mined diamond.
Because of this, a fab diamond displays the same brilliance, fire, and hardness as a natural diamond. Under normal viewing conditions, there is no visible difference between a fab diamond and a mined diamond.
Fab Diamond vs Lab Grown Diamond (Same Thing Explained)
There is no scientific difference between a fab diamond and a lab grown diamond.
“Fab Diamond” is simply a shorter, informal term.
“Lab Grown Diamond” is the official industry terminology.
Both describe a real diamond created in a laboratory.
When purchasing jewelry, you may see either term used, but in both cases, the stone is a genuine diamond with the same measurable properties as a natural diamond.
How Lab Grown Diamonds Are Made
Lab grown diamonds are created using advanced technological processes that replicate the natural conditions under which diamonds form inside the Earth. These methods allow carbon atoms to arrange themselves into the same crystal structure found in natural diamonds, producing stones that are physically and chemically identical.
Two main techniques are used in modern diamond laboratories: CVD and HPHT. Both methods result in genuine diamonds, but they differ in how the growth environment is created and controlled.
CVD Diamond Growth Process
CVD stands for Chemical Vapor Deposition. In this process, a thin diamond seed is placed inside a sealed chamber filled with carbon-rich gas.
The chamber is heated to very high temperatures, causing the gas molecules to break apart. Pure carbon atoms are then released and gradually attach themselves to the diamond seed. Layer by layer, these carbon atoms crystallize, forming a larger diamond.
This controlled growth allows precise management of:
Diamond purity
Crystal structure
Color development
CVD diamonds are known for their high clarity and excellent optical performance.
HPHT Diamond Growth Process
HPHT stands for High Pressure High Temperature. This method mimics the extreme pressure and heat found deep within the Earth’s mantle.
A small diamond seed is placed inside a press along with a carbon source. The press applies intense pressure and temperatures exceeding 1,500°C. Under these conditions, carbon melts and crystallizes around the seed, forming a diamond.
HPHT is the earliest method used to create lab grown diamonds and is still widely employed today.
Does Growth Method Affect Quality?
Both CVD and HPHT produce real diamonds with the same fundamental properties as natural diamonds.
The overall quality of a lab grown diamond depends more on:
Cut precision
Growth control
Post-growth treatment
Grading standards
Rather than the specific growth method itself.
Well-cut CVD and HPHT diamonds can both achieve excellent brilliance, fire, and durability.
Are Fab Diamonds Real Diamonds?
Yes. Fab diamonds are real diamonds in every scientific and gemological sense.
They are composed entirely of crystallized carbon arranged in the same atomic structure as natural diamonds. This identical crystal lattice gives fab diamonds the same optical behavior, hardness, and durability as mined diamonds.
From a physical and chemical standpoint, there is no difference between a fab diamond and a natural diamond.
Chemical & Physical Properties
Fab diamonds share all core properties of natural diamonds:
Pure carbon composition
Cubic crystal structure
Refractive index responsible for diamond brilliance
Thermal conductivity typical of diamond
These properties are what define a diamond, regardless of whether it formed underground or in a laboratory.
Because of this, fab diamonds respond exactly the same way as natural diamonds when tested using professional diamond testing instruments.
Hardness, Durability & Longevity
Diamonds — both natural and lab grown — rank 10 on the Mohs scale of hardness, making them the hardest known natural material.
This means fab diamonds:
Resist scratching
Maintain polish over time
Are suitable for everyday wear
With proper care, a fab diamond can last a lifetime and beyond, just like a natural diamond.
Fab Diamond vs Natural Diamond
Fab diamonds and natural diamonds share the same fundamental properties, but they differ in how they are formed. Understanding these differences helps clarify what truly matters when choosing between them.
The main distinction is origin, not composition.
Visual Differences
To the naked eye, there is no visible difference between a fab diamond and a natural diamond.
Both can display:
Exceptional brilliance
Sharp light reflection
Fire and sparkle
When properly cut, a lab grown diamond looks identical to a mined diamond of the same quality. Even trained professionals require specialized laboratory equipment to determine a diamond’s origin.
Structural Differences
Structurally, fab diamonds and natural diamonds are the same.
They share:
Identical atomic arrangement
Same crystal lattice
Same hardness and density
The only structural distinction is the growth environment:
Natural diamonds form underground over geological time
Fab diamonds grow in controlled laboratory conditions
This difference does not affect performance or durability.
Price Differences
One of the most significant differences between fab diamonds and natural diamonds is price.
Lab grown diamonds typically cost less than natural diamonds of equivalent quality. This price advantage allows buyers to:
Choose a larger carat size
Upgrade color or clarity
Invest more in design or setting
Without sacrificing beauty or durability.
Fab Diamond vs Moissanite
Fab diamonds and moissanite may appear similar at first glance, but they are fundamentally different gemstones. Understanding these differences helps you choose the stone that best matches your expectations.
Material Composition
Fab diamonds are composed of pure carbon, exactly like natural diamonds.
Moissanite is made of silicon carbide, a different compound with its own crystal structure and optical behavior.
Because of this difference, moissanite is not a diamond. It is a diamond alternative.
Sparkle & Fire Comparison
Fab diamonds produce a balanced combination of brilliance (white light reflection) and fire (colored light dispersion).
Moissanite tends to display:
Higher fire
More rainbow flashes
Some people enjoy this extra color, while others prefer the more classic sparkle of a diamond.
Fab diamonds deliver the same optical appearance as natural diamonds.
Which Should You Choose?
Choose a fab diamond if you want:
A real diamond
Traditional diamond sparkle
Maximum durability
Certification from major gemological labs
Choose moissanite if you prefer:
Lower cost
Strong rainbow fire
A diamond alternative
For those seeking an authentic diamond experience, fab diamonds are the correct choice.
Fab Diamond Certification & Quality Standards
Just like natural diamonds, fab diamonds can be independently graded and certified by recognized gemological laboratories. Certification ensures transparency, accuracy, and confidence in the quality of your diamond.
A grading report provides detailed information about the stone’s characteristics and confirms that the diamond is lab grown.
IGI & GIA Lab Grown Reports
Two of the most respected laboratories for lab grown diamond certification are:
IGI (International Gemological Institute)
GIA (Gemological Institute of America)
These laboratories evaluate lab grown diamonds using the same criteria applied to natural diamonds, including cut, color, clarity, and carat weight.
A certified fab diamond will include documentation verifying:
Laboratory-grown origin
Shape and measurements
Cut quality
Color grade
Clarity grade
Carat weight
This certification protects buyers and guarantees authenticity.
Understanding the 4Cs
The quality of a fab diamond is determined using the 4Cs:
Cut – How well the diamond is shaped and faceted. A well-cut diamond reflects light efficiently, creating brilliance.
Color – Graded from colorless to light yellow. Near-colorless stones appear white once set.
Clarity – Measures internal and external characteristics. Many inclusions are microscopic and invisible to the naked eye.
Carat – The diamond’s weight.
Balancing these four factors helps you select a diamond that offers the best visual beauty within your budget.
Why Choose a Fab Diamond?
Fab diamonds combine advanced technology with timeless beauty. They offer the same visual appeal and durability as natural diamonds, while providing additional advantages that make them an increasingly popular choice.
Better Value for Money
One of the strongest reasons to choose a fab diamond is value.
Lab grown diamonds typically cost significantly less than natural diamonds of comparable quality. This allows you to:
Choose a larger stone
Upgrade color or clarity
Invest more in design and craftsmanship
Without increasing your budget.
Consistent Quality Control
Because fab diamonds are created in controlled laboratory environments, their growth conditions can be carefully monitored.
This results in:
Predictable quality
High clarity potential
Stable color outcomes
Each stone can be selected to meet strict standards before being cut and polished.
Modern & Responsible Choice
Fab diamonds are produced without traditional mining processes.
For many buyers, this represents:
A more modern approach to luxury
Reduced environmental impact
A transparent supply chain
Fab diamonds align with contemporary values while preserving the beauty of classic fine jewelry.
How to Choose the Right Fab Diamond
Choosing a fab diamond is about balancing beauty, performance, and budget. While all lab grown diamonds share the same fundamental properties, differences in cut, color, clarity, and carat weight can significantly impact how a diamond looks in real life.
Understanding how these factors interact will help you select a diamond that offers exceptional visual appeal without unnecessary cost.
Choosing Cut (Most Important Factor)
Cut determines how well a diamond reflects light. Even a high-carat diamond can appear dull if poorly cut, while a well-cut smaller stone can appear bright and lively.
For maximum brilliance:
Round diamonds: Choose Excellent or Very Good cut
Fancy shapes (oval, pear, cushion, emerald): Look for stones described as Excellent, Very Good, or with strong symmetry and polish grades
A superior cut improves:
Sparkle
Light return
Face-up appearance
If budget is limited, prioritize cut before any other characteristic.
Choosing Color
Color grades measure the absence of yellow or brown tint.
General guidance:
D–F: Colorless (premium, icy white)
G–H: Near-colorless (excellent value, appear white once set)
I–J: Slight warmth, still attractive in many settings
For white gold or platinum settings, G–H offers an excellent balance between appearance and price. For yellow or rose gold, I–J can still appear beautifully white.
Choosing Clarity
Clarity describes internal inclusions and surface features.
Recommended ranges:
VVS1–VVS2: Extremely clean, higher cost
VS1–VS2: Very clean, excellent value
SI1: Can be eye-clean when well selected
Most buyers choose VS or eye-clean SI stones, as inclusions are invisible without magnification.
Avoid paying premiums for flawless grades unless rarity is important to you.
Choosing Carat Weight
Carat weight affects size, but not brilliance.
Because fab diamonds cost less than natural diamonds, you can often increase carat size without sacrificing quality.
Tips:
Prioritize cut before carat
Consider slightly under whole numbers (e.g., 0.90 instead of 1.00 carat) for better value
Compare millimeter measurements, not only carat weight
Two diamonds with the same carat weight can appear different in size depending on cut proportions.
Balancing the 4Cs
The best fab diamond is not defined by a single perfect grade, but by balance.
A common high-value combination:
Excellent cut
G–H color
VS2 clarity
Carat size based on budget
This combination delivers strong brilliance, clean appearance, and excellent value.
