How Are Lab-Grown Synthetic Diamonds Made?

Diamonds are made from highly organized carbon. Natural diamonds take around 1 billion to 3 billion years to form. How are lab-grown diamonds made? Lab-grown diamonds are created by applying heat and pressure to a diamond seed. This chamber replicates the conditions that are present inside the earth’s surface. The diamonds take around six to eight weeks to form. The diamonds are then cut, polished, and graded. It is virtually impossible for the naked eye to tell the difference between diamonds made in the lab and mined diamonds . They are a revolution in the diamond industry. Lab-Created Diamonds have many advantages over mined diamonds.

However, man made diamonds are often called by different terms, used interchangeably. For instance, lab-grown and lab-created often refer to the fact that these are manufactured in laboratories. And synthetic diamonds is a much broader term. While lab grown or lab created diamonds are real diamonds with similar properties as mined diamonds, synthetic diamonds could mean fake or imitation diamonds.

People often search online to understand how lab grown diamonds are made. That’s because they want to know about the authenticity of the diamonds. Whether they can confidently buy lab grown diamonds with trust. And how ethically the lab created diamonds are made.

What are lab grown synthetic diamonds?

Lab grown synthetic diamonds are real diamonds man made in controlled laboratory environments. Unlike mined diamonds that grow under the Earth and take millions of years, lab diamonds are created by scientifically replicating the natural process in laboratories. Growing lab diamonds takes only a few weeks to months.

Lab grown synthetic diamonds can be made using two processes -

Lab diamonds have the same chemical, physical, and optical properties as mined diamonds. However, lab diamonds are 30 to 50% more affordable than mined diamonds.

The Two Methods Used to Make Lab Diamonds

Chemical Vapour Deposition (CVD):

The CVD process is how lab diamonds are made to create gem-quality diamonds. The CVD process uses ultra-pure, rich carbon gases in a controlled environment or chamber. Some microwave lab grown diamonds are mentioned below: -

Low-pressure CVD (LPCVD)
Ultrahigh vacuum CVD (UHVCVD)
Plasma-enhanced chemical vapour deposition (PECVD)
Microwave Plasma Vapour Deposition (MPCVD)

CVD Process – Step-by-Step

The CVD lab diamond making process involves placing a diamond seed in the growth chamber.
This chamber is then filled with carbon-rich gases, such as methane and hydrogen.
The next step involves introducing heat in the chamber, which leads to the process of ionization and breaking of molecular bonds.
Next, the carbon atoms deposit onto the diamond seed, forming a lab grown diamond.

High Pressure High Temperature (HPHT):

In HPHT, the machines have the ability to build up a pressure of almost 60,000 atmospheres and a temperature of 2,500°C. It contains all the elements that are needed to grow a diamond. It includes a tiny diamond seed, highly refined graphite, and a catalyst mixture containing metals and powders. The catalyst inside reacts with added heat and pressure, resulting in a molten form. Pressure created diamonds cause the graphite (carbon) to dissolve. After this the cooling process takes place. It requires a controlled environment to produce a gem-quality diamond.

HPHT Process – Step-by-Step

The HPHT lab diamond making process starts with the placement of a diamond seed in a growth chamber.
The seed is then put through high temperatures and high pressure.
These conditions are similar to those under the Earth.
The carbon in the chamber melts and forms a diamond around the seed.
As the carbon begins to cool, it settles layer by layer and forms a larger diamond.

Diamond Press Technologies Used in HPHT

Cubic Press:

This technique uses many pistons that provide pressure from many different directions. How are lab diamonds created? This process ensures high-quality diamonds that mirror their natural counterparts.

The Cubic Press:

It distributes pressure uniformly across six faces
It minimizes pressure gradients
The carbon atoms have a more stable and consistent growth environment
The result is diamonds with fewer internal inclusions
Belt Press

The Belt Press uses two opposing anvils to apply pressure from the top and bottom. The Cubic Press applies force simultaneously from all six directions.

BARS Press

The BARS Press is more precise than the Belt Press. It involves a split-sphere mechanism that applies pressure through fewer contact points.

HPHT vs CVD: Differences

Feature	HPHT	CVD
Process	Mimics natural diamond formation process including pressure and temperature	Chemical process in growth chamber
Growth time	Faster growth cycles	Slower growth
Applications and usage	Premium quality hence useful for jewelry, fashion, engagement and wedding rings	Useful for regular wear jewelry, industrial usage
Post-growth treatment	Requires less to no treatment	Requires treatment to remove brown tint
Size capability	Efficiently produces larger stones (3+ carats) with consistent quality	More challenging and expensive to produce larger sizes
Cost	Cost effective for producing high-quality diamonds at scale	Higher production costs, especially for larger stones

How long does it take to grow a lab diamond?

While natural diamonds take billions of years to grow under the surface of the Earth, lab grown diamonds grow within a few weeks in laboratories. Advanced science has found ways to replicate the process that forms diamonds under the Earth, in laboratories, using machines and equipment designed to grow diamonds.
The exact time required to create each diamond depends on various factors, such as the method used (HPHT or CVD), the size or carat weight of the diamond, and the quality of the diamond seed, among other factors. While HPHT diamonds grow within three to four weeks, CVD diamonds take longer to grow.

Lab grown diamonds vs. natural diamonds: Formation comparison

Natural diamond formation	Lab grown diamond formation
Takes billions of years to form.	It takes three to four weeks.
The diamonds form 100 miles or more under the surface of the Earth.	Laboratories use either the HPHT method or the CVD method.
The diamonds are carried to the surface of the Earth due to volcanic activities.	A tiny diamond seed crystal is placed inside a diamond-growing chamber.
Most diamonds near the Earth’s surface have been mined and hence, new natural diamonds are rare.	The environment and process is controlled. High temperature and high pressure are created inside the chamber.
It is hard to trace mined diamonds, where they come from, whether they are blood diamonds or ethical diamonds.	Tracing lab grown diamonds is easy because each diamond comes with a certificate stating its origin, lab details, method used, etc.
Mined diamonds are graded by the GIA, IGI, among other institutions.	Lab grown diamonds are also graded by the same institutions using the same methods and parameters.

The environmental impact of lab created diamonds

Energy consumption

HPHT and CVD diamonds consume large amounts of energy because they require high temperature and pressure. The energy consumed also depends on the laboratory where the diamond is produced.

Devoid of negative impact of mining

Lab grown diamonds do not have the kind of negative impact that mined diamonds have. For instance, it does not cause land disruption, soil erosion, habitat destruction, etc. Lab diamonds are not associated with war, political or social concerns.

Renewable energy advantage

Lab diamond manufacturing facilities can use renewable energy, such as solar, wind, and hydroelectric power, to power the process of lab creation. This way, the lab grown diamond can collectively reduce the carbon footprint that is created by the process of growing diamonds. Many modern and progressive lab grown diamond manufacturing facilities are using renewable energy in their labs.

The Future of Lab-Created Diamonds

The lab grown diamonds industry has been evolving over the last couple of years, thanks to technological advancements and changing consumer preferences. Here are some trends that are shaping the future of lab grown diamonds:

Technological advancements, including advanced CVD and HPHT processes, are leading to faster growth times, larger carat sizes, and enhanced diamond colours.
Sustainability focus in the diamond industry is gaining prominence, leading to higher transparency in supply chains and helping businesses reach carbon-neutral goals faster.
The market for lab grown diamonds is undergoing significant changes, enhancing price stability and increasing acceptance of lab grown diamonds.

Conclusions

Lab grown diamonds are likely to become more acceptable and accessible, whether they are chosen for ethical or environmental reasons. If you’re looking for the best quality lab grown diamonds, explore Grown Diamond Corporation.
