When a lab-grown diamond is sent to a laboratory, it undergoes an examination to determine whether it is natural or created in a laboratory. Gemologists conduct this assessment using the internationally recognized 4C evaluation standard applied worldwide.

• Carat: Indicates the weight of the diamond.
• Clarity: Evaluates the internal and surface flaws within the diamond.
• Color: Determines the color grade of the diamond.
• Cut: Evaluates the quality of the diamond’s cut.

Gemologists use advanced testing methods such as spectroscopy to ascertain how the diamond was grown, whether through high-pressure, high-temperature (HPHT) methods or chemical vapor deposition (CVD). This information is then included in a report. The Lab-Grown Diamond Report specifies the growth method of the diamond and provides evidence of any post-growth treatments.

Diamonds, whether lab-grown or natural, can undergo various treatments to achieve desired characteristics. For instance, processes are employed to obtain fancy colors like pink, blue, green, or yellow or to enhance the color of a natural diamond from D to Z.
