What Is A Lab-Grown Diamond?

A lab-grown diamond, also known as a synthetic diamond, is a diamond that is produced in a controlled environment, rather than being mined from the earth. Lab-grown diamonds are chemically and physically identical to natural diamonds, and they have the same brilliance, fire, and durability.

How are lab-grown diamonds created?

There are two main methods for growing lab-grown diamonds: High-pressure, high-temperature (HPHT) synthesis and chemical vapor deposition (CVD).

  • HPHT synthesis: This method replicates the conditions under which diamonds form naturally, subjecting a carbon source to high pressure and temperature. The carbon source can be a diamond seed or a carbon-rich material such as graphite.
  • CVD: This method involves depositing layers of carbon atoms onto a diamond seed using a plasma or chemical vapor. The carbon atoms are supplied by a gas that is broken down into its constituent elements.

What are the benefits of lab-grown diamonds?

There are several potential benefits to choosing lab-grown diamonds over mined diamonds:

  • Affordability: Lab-grown diamonds are typically much more affordable than mined diamonds. This is because the cost of mining and processing diamonds is high, and the supply of mined diamonds is limited.
  • Ethical and sustainable: The mining of diamonds can have a negative impact on the environment and the communities where it takes place. Lab-grown diamonds are produced without any of these negative impacts.
  • Transparency: The provenance of lab-grown diamonds is often much clearer than that of mined diamonds. This is because lab-grown diamonds are produced in controlled environments, and their production is well-documented.

Are lab-grown diamonds real diamonds?

Yes, lab-grown diamonds are real diamonds. They have the same chemical and physical properties as mined diamonds, and they are indistinguishable from mined diamonds to the naked eye. In fact, the Federal Trade Commission (FTC) ruled in 2018 that lab-grown diamonds are diamonds.
