Lab-grown diamonds are graded using various grading systems, including,
❖ GIA (Gemological Institute of America): GIA is a renowned and globally recognized
gemological laboratory. They assess and provide grading reports for lab-grown
diamonds, evaluating their quality based on the 4Cs (carat weight, color, clarity, and cut).
❖ IGI (International Gemological Institute): IGI is another well-established gemological
laboratory that offers grading services for lab-grown diamonds. Their reports provide
information about the diamond's characteristics, including the 4Cs, as well as a detailed
description of its cut, symmetry, and fluorescence.
❖ HRD (Hoge Raad voor Diamant): HRD is a respected diamond grading institute based in
Antwerp, Belgium. They provide grading reports for lab-grown diamonds, assessing their
quality based on the 4Cs and additional factors such as polish, symmetry, and
fluorescence.
❖ GCAL (Gem Certification & Assurance Lab): GCAL is a leading gemological laboratory
that offers grading services for both lab-grown and mined diamonds. Their reports
provide detailed information on the diamond's 4Cs, as well as additional factors like light
performance and diamond identification.GSI (Gemological Science International: GSI is
an internationally recognized gemological laboratory that grades lab-grown diamonds
based on the 4Cs. Their reports include detailed information about the diamond's quality
characteristics and provide an assessment of its overall grade.
❖ EGL (European Gemological Laboratory): EGL is a widely known gemological laboratory
that offers grading services for lab-grown diamonds. Their reports provide information
about the diamond's 4Cs and additional factors like fluorescence, symmetry, and polish.
It's important to note that the grading criteria and standards may vary slightly between different laboratories. However, these grading institutes play a crucial role in providing reliable and standardized assessments of lab-grown diamonds, helping consumers make informed decisions based on the quality and characteristics of the stones. When purchasing a diamond, it is advisable to choose a diamond that has been certified by a reputable and trusted grading laboratory to ensure the accuracy and reliability of the diamond's characteristics.
