What are Lab Diamonds ? Mina D explains

Lab diamonds, also known as lab-grown diamonds, are diamonds that are created in a laboratory rather than being mined from the earth. They have the same physical, chemical, and optical properties as natural diamonds, but they are produced in a controlled environment using advanced technology.

How are Lab Diamonds Created?

Lab diamonds are created using two main methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

In the HPHT method, a small diamond seed is placed in a chamber and exposed to high pressure and high temperature. Carbon is then added to the chamber, and over time, the carbon atoms attach to the diamond seed and form a larger diamond crystal.

In the CVD method, a thin slice of diamond seed is placed in a chamber and exposed to a mixture of gases. These gases are then ionized, creating a plasma that breaks down the molecular bonds of the gases. Carbon atoms from the gases then attach to the diamond seed and gradually build up to form a larger diamond.

What are the Advantages of Lab Diamonds?

Lab diamonds offer several advantages over natural diamonds:

  1. Ethical and Environmental Considerations: Lab diamonds are conflict-free and have a smaller environmental impact compared to mined diamonds.
  2. Price: Lab diamonds are typically more affordable than natural diamonds of similar quality.
  3. Quality Control: Lab diamonds are created in a controlled environment, allowing for greater consistency in terms of color, clarity, and cut.
  4. Availability: Lab diamonds are readily available and can be produced in larger sizes and quantities. Rather than taking billions of years to mine, it takes 10-12 weeks to grow into the rough diamond. The rough diamond is then cut and polished to the specifics of the diamond size, quality and shape.

Are Lab Diamonds Real Diamonds?

Yes, lab diamonds are real diamonds. They have the same chemical composition, crystal structure, and physical properties as natural diamonds. The only difference is their origin.

How Can You Tell if a Diamond is Lab-Diamond?

Lab-grown diamonds can be identified using various gemological techniques. Gemologists can examine the diamond's growth patterns, inclusions, and other characteristics to determine if it is natural or lab-grown. Additionally, many lab-grown diamonds are laser inscribed with a unique identification number to differentiate them from natural diamonds. They cannot be identified by any other means other than gemological testing. 


Lab diamonds are a fascinating alternative to natural diamonds. They offer ethical and environmental benefits, are more affordable, and provide consistent quality. Lab diamonds and Lab diamond jewelry are the wave of the future.
