What is a Lab Grown Diamond?

 Lab grown diamonds, or also called lab created diamonds because they are created in a laboratory, unlike mined diamonds that occur naturally and are extracted from the earth. They come in various shapes and sizes and have almost identical chemical structures. There is no visible difference between these two types of diamonds, as lab diamonds look and feel precisely like mined diamonds. Lab-created diamonds are in fact real diamonds and offer the same brilliance, sparkle, and shine of a mined, mined diamond.

Mined diamonds are formed over millions of years due to intense heat and pressure, while lab-grown diamonds can be produced in just a few weeks. Mined diamonds may contain a little nitrogen, but synthetic diamonds do not. Despite their similarities, there is a significant price difference between the two.

Lab-grown diamonds are not guaranteed to be perfect, whether a diamond gown in a lab or mined from the earth- is unique. To distinguish between inclusions and blemishes and variations in color, consumers can rely on the certification which evaluates the quality of the diamond based on the 4Cs: carat, color, clarity, and cut. The certification will prominently label lab-grown diamonds. When it comes to choosing between lab-grown and mined diamonds, it ultimately depends on the buyer's priorities. In most cases, they look the same to the naked eye, but some people may perceive a mined diamond as more "real."

How do they compare

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

How are Diamonds Grown in a lab?

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.

HPHT Process For Growing Diamonds in a Lab

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.

CVD Process For Growing Diamonds in a Lab

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.

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

Lab diamonds are a budget-friendly option without sacrificing quality, as they are significantly less expensive than mined diamonds due to industry competition and the unlimited production of lab diamonds.

Lab Diamond Ehtics and Sustainability

Sustainability is a controversial topic, as there is no consensus on whether lab diamonds are more sustainable than mined diamonds. While man-made diamonds offer fewer ethical concerns, there are concerns about the sustainable practices of each lab. In terms of appearance but do not overlook the option of lab-created diamonds as they could provide the opportunity for a beautiful ring with a much larger diamond.

Frequently Asked Questions

What are the benefits of lab-created diamonds?

Lab-created diamonds are indistinguishable from "mined" diamonds in terms of their appearance, texture, and chemical composition. Some people believe that they are a more eco-friendly option.

Is a lab diamond as strong as mined diamond?

Laboratory diamonds are as strong and as hard as mined diamonds, both scoring a 10 on the Mohs hardness scale.

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

With naked eyes, even jewelers and gemologists cannot tell a mined diamond from a lab-created one. With specialized equipment, however, a gemologist may be able to spot small inclusions that indicate a lab-created diamond.

Can lab diamonds pass a diamond tester?

Yes. Lab diamonds are real diamonds, made from pure crystallized carbon, and will pass any tests to prove such.

determining the growth source by inclusions

It is essential to note the growth origin of a diamond cannot be determined by the presence or absence of inclusions alone. For example, just because a diamond is free of inclusions does not mean it is lab-grown. Conversely, just because a diamond is highly included does not mean it is natural. Both natural and laboratory-grown diamonds can occur in all clarities.

Do Lab diamonds have the same brilliance as mined diamonds?

Yes, lab diamonds possess the same shine and sparkle as mined diamonds since they have the same cutting process. They also have the same range of color and clarity and are rated on the same scale. The only difference is how they're created.

Diamond Guides
Are lab-grown diamonds GIA or IGI certified?

Cut, Clarity, Color, and Carat weight are the same for lab diamonds as mined diamonds. IGI is the primary certification for lab created diamonds. The GIA more recently began certifying lab-grown diamonds, so there are fewer diamonds with GIA certification. 


Everyone loves a diamond alternative, and why not? It is very appealing to find a gemstone that looks like a diamond for a significantly lower investment. The popularity of lab created diamonds in the market has created some confusion. So let us clear it up.
