There is a misconception about lab diamonds being synthetic. But that is not true, and they are as genuine as natural diamonds. However, based on their distinct origins and characteristics, they are different from each other.
When it comes to differences between lab grown vs natural diamonds, the most common difference is that lab-produced diamonds are a more affordable alternative to mined diamonds that are visually and physically indistinguishable from the real thing.
To understand which one is the right choice for you, we suggest you go through each factor, which can clarify your doubts.
Key Differences Between Lab Grown vs Natural Diamonds

By focusing on several key factors, you will have a much better understanding of what makes them different from each other.
Origin
Lab Grown Diamonds
Lab grown diamonds are produced in highly specialized laboratory facilities using cutting-edge equipment that simulates the high-pressure and high-temperature conditions present deep under the mantle of the Earth. In most cases, the production process takes between six and ten weeks.Ā
By depositing carbon onto a microscopic “seed” diamond crystal, powerful presses create pressures that are more than one million per square inch (psi) and temperatures that are greater than two thousand five hundred degrees Celsius (°C).Ā
This allows the laboratories to manufacture diamonds with size, cut, clarity, and optical qualities that may be adjusted to the customer’s specifications. For natural diamonds, reaching this degree of control is not feasible.
Natural Diamonds
Natural diamonds, on the other hand, are only found under very particular circumstances and are located deep down, between 140 and 190 kilometers below the surface of the earth’s surface.
The crystallization of carbon atoms into diamonds takes place throughout billions of years at depths of more than 90 miles. This is made possible by the high heat that emanates from the core of the earth and the severe pressure that is caused by the huge weight of the rock strata that lie above it.
Natural diamonds are believed to have originated at a depth that is far deeper than any drilling that has ever been conducted. The oldest diamonds are thought to be around three billion years old.
The kimberlite and lamproite pipes are the conduits via which they are transported to the surface quickly during volcanic eruptions. Skilled diamond cutters shape a raw diamond while the diamond’s intrinsic brightness, fire, and scintillation are carefully preserved.

Structural Composition
Lab Grown Diamonds
Diamonds that are developed in laboratories have outstanding chemical purity, optical transparency, and physical structure. This is because they are engineered in settings that are precisely regulated.
The production procedure reduces the number of contaminants, such as nitrogen or boron, that affect color grading. Mineral inclusions, fissures, and growth lines are examples of internal crystal flaws that are not present in lab diamonds.
This is one of the factors that contribute to better gem quality grading. Laboratory diamonds, on the other hand, do not have the intricate natural development patterns and crystal signatures that are present in natural diamonds because of the controlled circumstances being used.
Natural Diamonds
The chemical and physical composition of natural diamonds may vary substantially depending on their genesis history in different geologic environments. Most of them include microscopic fluids or mineral inclusions that point to their underground origins.
Each natural diamond is unique in its own way, and these “birthmarks” affect the clarity grades as well. In diamonds, trace elements like boron and nitrogen may be found at trace levels and can affect the final color grading.
To optimize carat weight and bring forth the diamond’s inherent brightness, cutters must meticulously work around any internal imperfections. It is precisely because of these flaws that natural diamonds are so highly valued for their uniqueness.
Visual Appearance
Lab Grown Diamonds
Lab diamonds may be developed in a controlled environment, which allows them to have outstanding clarity, colorlessness, and light performance that is comparable to or even surpasses that of rare natural diamonds. Even the finest gem-grade grading is not able to match the extraordinary brightness and fire that they show.
Natural Diamonds
The vast majority of natural diamonds include small mineral traces that make them seem somewhat different in hue. Although the rarest ones are colorless, the majority of them have warm colors such as yellow, brown, or gray that impair their grading capabilities.
Clarity scores are lowered as a result of the prevalence of errors and inclusions. The most beautiful natural diamonds, however, have a dazzling brightness that shines through these defects when they are cut just right.
Grading
Lab Grown Diamonds
Lab diamonds are evaluated using the 4Cs grading standards, which include clarity, color, cut, and carat weight. These criteria are based on the Gemological Institute of America (GIA) or other gem lab assessment procedures, such as measuring light performance, analyzing inclusions, material analysis, and so on. The chemical purity and physical perfection that arise from supervised manufacture ensure that they typically obtain top ratings for clarity and color.
Natural Diamonds
On the other hand, natural diamonds are graded according to the 4Cs, with clarity and color being highly influenced by natural imperfections that occurred throughout the creation history of the diamond.Ā
The quality of the cut is also very important for increasing the carat weight. Proper cuts of natural diamonds reveal mesmerizing brightness that emanates through slight defects, even though only a small percentage of natural diamonds get the finest color and clarity ratings.
Manufacturing Process
Lab Grown Diamonds
Diamond seed crystals are put in metal alloy capsules and exposed to great heat (2500 degrees Celsius) and pressure (more than one million pounds per square inch) in highly constructed growth chambers.
This process is repeated to permit the production of diamond crystals. To develop a diamond with tailored optical characteristics that weigh up to nine carats, the complete procedure takes between six and eight weeks.
Natural Diamonds
At a depth of around 90 miles below the surface of the earth, where intense pressures condense carbon into diamonds, natural diamonds go through a formation process that takes place over centuries or perhaps billions of years.
Deep volcanic eruptions bring the diamond-bearing rock formations closer to the surface of the earth because of their proximity. Following this, the diamonds are extracted using bulk processing, after which they are graded according to carat, color, and clarity.
Light Performance
Lab Grown Diamonds
Using cutting and polishing techniques that have been carefully devised, light return, brightness, and fire are all improved. Lab diamonds have outstanding brilliance since light is reflected back in a symmetrical manner via the perfect crown and pavilion cuts, and the crystal structure is colorless and unaffected by impurities.
Natural Diamonds
When it comes to enhancing the light performance of a natural diamond, cut quality is also of the highest priority. Inclusions have the potential to significantly obstruct the flow of light; yet, in the case of exquisite natural diamonds, the brightness and fire that are brought out by precise cutting are outstanding. In addition, the distinctive growth lines provide enticing flashes of light.

When compared to lab-grown diamonds, natural diamonds charge much higher prices across the board for all forms of jewelry. The price difference between natural diamonds vs lab grown diamonds is about two to three times more for similar carat sizes and settings.
When compared to the availability and efficiency of making lab diamonds, natural diamonds are characterized by their prestige, history, and exclusivity. This is the reason why lab diamonds are more desirable. Nevertheless, lab-grown diamonds have the potential to provide excellent value at very reduced price points.
Why Preference of Buying Lab Diamonds Increased in Recent Years?
For both pragmatic and ideological grounds, reflecting shifts in generational perspectives, the recent surge in favor of lab-grown diamonds over mined diamonds has been remarkable.
Practically speaking, lab diamonds are now more accessible and affordable than ever before because of advancements in manufacturing technology. They were once sold at a premium price, but are now up to 40% off, making them much more reasonable for shoppers. They are just as beautiful and sparkling as the most expensive genuine diamonds.
However, there is a more fundamental change in mindset and objectives at work here as well, particularly among millennials and Gen Z consumers, who place a higher value on diversity, ethics, and sustainability than previous generations. Lab diamonds are in perfect harmony with these principles, and it shows.
Compared to mining, which uses up valuable resources and has an effect on local ecosystems and people, lab diamonds have a 99% smaller carbon footprint, which is something that younger, more progressive consumers want. Their aspirations for customization are also satisfied by the made-to-order flexibility. They prioritize social influence and significance above mere status when making purchases.
This newfound inclination shows how the ideals of the younger generation are changing the definition of luxury. They consider it a badge of honor to associate the ethical manufacturing of the jewelry they buy, whether it’s an engagement ring or something else entirely, with their major purchases.
This demographic is driving growth in the lab diamond industry across all jewelry types because of their increasing disposable income and a fascination with the symbolism of lab diamonds in addition to their dazzling quality and affordable costs.
