Lab-Grown Diamonds

Diamonds that have been “grown” in a controlled laboratory environment are known as lab grown diamonds. They are made of the same chemical components as natural diamonds (carbon atoms arranged in a specific pattern), but rather than being formed deep within the earth’s crust, lab made diamonds are created in a laboratory.

Lab-grown diamonds are chemically identical to natural earth-made diamonds, their appearance, quality, and durability are virtually indistinguishable.

How Long Have Lab-Grown Diamonds Been Around?

Since the 1950s! At first, they weren’t gem quality to set into jewelry but were mostly used for industrial cutting, because diamond is so hard. It has taken decades to perfect the process to grow gem quality diamonds which meet mined diamonds in terms of desirability and size.

It All Starts With Carbon

Scientists realized that diamonds were formed from pure carbon is when the attempts to reproduce diamonds started.

How Are Lab-Grown Diamonds Grown?

Laboratory made diamonds are created in an artificial setting that mimics how diamonds are made naturally below the Earth’s mantle. There are two methods used to create lab diamonds: CVD (chemical vapour deposition) and HPHT (high pressure high temperature).

Learn how scientists have created a way to mimic the natural growth of a diamond within a laboratory, and how these processes produce authentic lab diamonds, identical to those found in nature.

What Is The Process Of High Pressure High Temperature (HPHT) Diamonds?

With HPHT, the technicians place a diamond “seed” (a small portion of a diamond crystal) into a graphite box which then simulates nature by applying high amounts of heat and pressure, melting the graphite into pure carbon and thus, creating a larger diamond crystal.

What Is The Process Of Chemical Vapor Deposition (CVD) Diamonds?

Chemical Vapor Deposition (CVD), a material is deposited from a gas (usually a mixture of hydrogen and methane), onto a diamond plate. A chemical reaction then takes place, producing deposits that grow onto the diamond plate. These processes take on average a few weeks to grow a rough diamond crystal ready for cutting.

Chemical Vapor Deposition (CVD) Process Of Diamonds

CVD requires a process seed to act as the foundation for chemical deposition, such as a thin slice of diamond or a graphite source.

Lab-Grown Diamonds Vs Mined Diamonds Vs Simulant Diamonds

Mined diamonds and lab-grown diamonds are identical – chemically, physically, & optically. Only the origin is different! One is grown above ground, and the other is grown underground. Lab created diamonds can be distinguished from natural diamonds only with tests using specialized equipment.

Lab created diamonds available for purchase should always come with a gem certification identifying them as laboratory grown. Simulants such as Cubic Zirconium, Moissanite and diamond-coated materials are in no way a diamond – the reason they cost much less. Online companies selling lab-created gems often misrepresent their product as a diamond.

Ours are type IIa which are the rarest and most valued of all real diamonds. Diamonds are categorized into four types: Type Ia, Type Ib, Type IIa, and Type IIb. Diamonds that are IIa contain no measurable amount of nitrogen in the crystal structure. This impurity is what imparts a tint to “would be” colorless diamonds.

Why Choose Lab-Grown Diamonds?

Lab-grown diamonds offer great value, as they are more affordable than natural diamonds of comparable size and quality.

Eco Friendly

Lab-grown diamonds require less space and resources to produce stones than that of the monolith mines that wreak havoc on local ecosystems.


Lab-grown diamonds offer excellent value and are 30-50% more affordable than mined diamonds of comparable size and quality.


Lab-grown diamonds never fund foreign conflict. Further, work conditions are carefully regulated and never exploit child laborers.

Price Comparison Of Mined Diamonds And Lab-Grown Diamonds

In comparison, lab-grown diamonds can typically cost 50-70% less than natural, mined diamonds. This percentage difference is based on a few factors. For one, the demand for mined diamonds remains much higher than for lab-grown diamonds and the market has a regulated supply, preventing too much supply from reaching the market at once and lowering the price.

For lab-grown diamonds, their awareness is much lower but they’ve been fast increasing in popularity. The process to make them has also gone through repeated innovations and technological advances that have drastically reduced the production costs.

Our lab grown diamonds are certified by the most esteemed laboratories in the world; GIA, IGI & GCAL.


GIA is an acronym for the Gemological Institute of America, considered the world’s leading geological research institute. The GIA tests diamonds and grades them based on the 4 C’s: carat weight, cut, color, and clarity. Testing is conducted under stringent guidelines not to miss any flaws. The institute then files a test report and signs off on the diamond’s quality. The diamond is then considered “GIA certified.”

IGI is an acronym for the International Gemological Institute. IGI Diamond Reports give an accurate assessment of a diamond’s cut, color, clarity and carat weight according to strict international standards. IGI screens every diamond using state of the art technologies to determine naturally mined, laboratory grown or simulant origin.
