Lab Grown Diamonds

Lab-Grown Diamonds are optically, chemically, and physically, identical to natural diamonds and are created in a lab by scientists. Lab-grown diamonds provide the same luxurious diamond at flexible price points to fit anyone’s lifestyle. Lab-grown diamonds also offer the opportunity of a larger carat weight at lower costs.

How Are Lab-Grown Diamonds Created?

Lab-Grown Diamond manufacturers operate in highly controlled lab environments using one of two methods: High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD).

Both processes begin with a diamond seed and result in a Lab-Grown Diamond. During the HPHT method, the scientist places the diamond seed in a growth chamber (apparatus), heats it to 2,700–3,100 degrees Fahrenheit, and exposes the seed to a pressure of 725,000 pounds per square inch, similar to the process that takes place in Earth’s mantle. The diamond seed remains under these intense conditions for varying lengths of time.

The CVD method of Lab-Grown Diamond creation begins with flat diamond slabs placed in a reactor. The reactor is injected with Methane gas. The gas is exposed to microwaves which cause it to break down into its comprising atoms and generate a carbon-rich plasma cloud. The carbon atoms in the plasma connect with the diamond slabs and create new layers, resulting in slow vertical growth.

Both the HPHT process and the CVD process produce Type IIa colorless Lab-Grown Diamonds, equal to some of the rare and sought-after types of Natural Diamond. These processes can also be adjusted to produce colored Lab-Grown Diamonds.

How do I tell if a lab-grown diamond is real?

Lab-grown diamonds are real diamonds. They are made up of a single element, carbon, just as their natural counterparts and have the same optical and physical properties. Advanced testing and screening are needed to distinguish between lab-grown diamonds and natural diamonds.

What is the difference between a natural diamond and a lab-grown diamond?

The only difference between a natural diamond and lab-grown diamond is how they are grown. Natural diamonds are grown and found in nature with little to no human intervention. Lab-grown diamonds, on the other hand, are grown in a lab with the help of scientists.
