Understanding Lab-Grown Diamonds: Your Comprehensive Guide

What is a Lab-Grown Diamond?

Lab-grown diamonds, also known as lab-created diamonds, are revolutionizing the diamond industry. Created in a lab, these diamonds mimic the properties of natural diamonds, which take millions of years to form in the earth. They share the same chemical, physical, and visual qualities as mined diamonds, making them visually identical. Their emergence in the market is significantly influencing diamond trends and choices, offering a high-tech and ethically appealing alternative to traditional diamond mining methods. This innovation marks a pivotal shift in how diamonds are perceived and valued in the jewelry market.


Let's dive into the fascinating processes of Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT), the two main methods used in crafting these stunning gems. Learn how these processes replicate the natural diamond-growing conditions, resulting in beautiful and high-quality diamonds.


Lab diamonds are created artificially in a laboratory instead of naturally occurring and mined from the earth. In the laboratory, there are two processes used to create diamonds; Chemical Vapor Deposition and HPHT (High Pressure High Temperature). Diamonds made by Chemical Vapor Deposition are the same as natural diamonds.


Diamonds require one essential element for growth: Carbon (C). For diamonds grown by the HPHT process, pure carbon powder is pressed into a growth capsule and subsequently placed in a growth chamber. Under extreme heat (1300 - 1600 °C) and pressure a diamond crystal will grow, atom by atom, day after day. Many large stones, up to 10.00 carats rough, can be produced in one run of less than two weeks.


The Chemical Vapor Deposition process begins with a thin diamond wafer being placed inside a vacuum chamber. Next, a mixture of gases containing hydrogen and methane, which provide the source of carbon, are heated at just the right pressure until they vaporize and the carbon settles onto the wafer, layer by layer, like rain, to form a uniform coating of diamond.

The CVD process has developed significantly in the last couple of years, yielding high quality large diamonds. This development has allowed CVD diamonds to dominate the market.


Explore the similarities and differences between lab-grown and natural diamonds. Understand how they compare in terms of appearance, strength, and value, and why lab-grown diamonds are often more budget-friendly.

Lab-Created Diamonds vs Mined Diamonds

The biggest differences are the source, sustainability, and pricing. Here's how they compare.

About Natural Diamonds

Formed formed by the heat and pressure of the Earth, around 1 to 3 billion years ago, find out about natural diamonds.

Comparing Cost of Lab Diamonds and Natural diamonds

When comparing the costs of lab-grown and natural diamonds, lab diamonds emerge as a more budget-friendly choice without compromising quality. This price difference is primarily because lab diamonds are produced through efficient technological processes, leading to a more controlled and potentially limitless production. This contrasts with the exhaustive and expensive mining operations required for natural diamonds. The competitive nature of the lab-grown diamond industry further contributes to more affordable pricing, offering consumers high-quality diamond options at a reduced cost compared to their mined counterparts.

Lab Diamond Ehtics and Sustainability

The ethics and sustainability of lab-grown diamonds is a nuanced topic. While they are generally viewed as having fewer ethical concerns compared to mined diamonds, particularly in terms of environmental impact and labor practices, there are still considerations regarding the sustainability practices of individual labs. Each lab may have different environmental footprints, which is an important factor in assessing their overall sustainability. Moreover, lab diamonds, with their more accessible pricing, offer consumers the possibility of choosing larger, high-quality diamonds that might have been out of reach if they were naturally mined. This aspect makes lab-grown diamonds an increasingly popular choice for those seeking both ethical and aesthetically appealing options.

Lab Created Diamonds Frequently Asked Questions

What are the benefits of lab-created diamonds?

Lab-created diamonds offer several advantages. Firstly, they are virtually identical to mined diamonds in appearance, texture, and chemical composition, making them an attractive alternative. They are also considered a more eco-friendly option, as their production involves fewer environmental impacts compared to traditional diamond mining. Additionally, lab diamonds typically come at a lower cost, providing greater accessibility to high-quality diamonds.

Is a lab diamond as strong as mined diamond?

Lab diamonds match the strength and hardness of mined diamonds, both scoring a perfect 10 on the Mohs hardness scale. This means lab-grown diamonds are just as durable and suitable for everyday wear as their natural counterparts.

Can a jeweler tell if a diamond is lab-created?

It is challenging for jewelers and gemologists to differentiate between lab-created and mined diamonds with the naked eye. However, using specialized equipment, experts can identify subtle differences, such as specific inclusions or growth patterns, that may indicate a diamond is lab-created.

Will a lab created diamonds pass a diamond tester?

Lab-created diamonds are composed of the same crystallized carbon as natural diamonds and will pass standard diamond tests. These tests are designed to detect real diamonds based on their physical and chemical properties, which lab diamonds share with mined diamonds.

Do Inclusions indicate the Diamond Source?

In determining the origin of a diamond, the presence or absence of inclusions is not a definitive indicator. Inclusions, which are natural imperfections, can be found in both lab-grown and mined diamonds. A diamond being inclusion-free doesn't necessarily mean it's lab-grown, and similarly, a diamond with many inclusions isn't automatically a natural, mined diamond. Diamonds of all types can exhibit a range of clarity levels. Therefore, the evaluation of a diamond's origin involves more than just assessing its inclusions.

Do Lab diamonds have the same brilliance as mined diamonds?

Lab-grown diamonds match the brilliance, shine, and sparkle of mined diamonds, thanks to the identical cutting processes they undergo. They also exhibit a similar range of color and clarity, and are evaluated on the same grading scale as natural diamonds. The primary distinction lies in their origin, with lab diamonds being created in controlled laboratory environments as opposed to being mined from the earth.

Diamond Guides
Are lab-grown diamonds certified?

Lab-grown diamonds, like their mined counterparts, are subject to certification by reputable organizations such as the International Gemological Institute (IGI) and the Gemological Institute of America (GIA). IGI has been a prominent certifier for lab-created diamonds, providing detailed reports on their cut, clarity, color, and carat weight. GIA, traditionally known for certifying natural diamonds, has also begun certifying lab-grown diamonds. Although GIA-certified lab diamonds are fewer in number, they are gaining prevalence in the market.


The growing popularity of lab-created diamonds has introduced some confusion in the market, particularly regarding their distinction from natural diamonds and other diamond alternatives. These lab-grown gems offer a visually and chemically similar experience to natural diamonds at a more accessible price point, making them an attractive option for many. Here we aim to clarify the differences and unique qualities of lab-created diamonds compared to other alternatives, highlighting their appeal as both a budget-friendly and aesthetically comparable choice to traditional diamonds.
