IGI certification ensures that buyers receive accurate and reliable information about the quality of their lab-grown diamonds, providing confidence in their purchase.

IGI diamonds are real. The International Gemological Institute grades both natural and lab-grown diamonds. An IGI certified diamond, whether lab-grown or natural, is a genuine diamond with verified physical and chemical properties. The certification confirms the authenticity and quality of the diamond.

Yes, it is perfectly okay to buy an IGI certified diamond. IGI is known for its stringent grading standards and comprehensive certification process. Buying an IGI certified diamond ensures you are getting a high-quality stone that has been thoroughly evaluated for its cut, color, clarity, and carat weight.

The best IGI cut grade is “Ideal.” An Ideal cut grade signifies that the diamond has been cut to optimal proportions and symmetry, maximizing its brilliance, fire, and scintillation. This grade is given to diamonds that exhibit the highest level of light performance, making them exceptionally beautiful and desirable.

This number corresponds to the IGI certification report and can be used to verify the diamond’s authenticity and grading details. The inscription is microscopic and does not affect the diamond’s appearance.

IGI rates diamonds based on the 4 Cs: cut, color, clarity, and carat weight. The cut is graded from Excellent to Poor, color from D (colorless) to Z (light yellow or brown), and clarity from Flawless (FL) to Included (I). Carat weight is measured to the hundredth decimal. These ratings provide a comprehensive overview of a diamond’s quality.

IGI does not make diamonds; it grades them. However, the lab-grown diamonds that IGI grades are typically made in controlled laboratory environments using advanced technologies like High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). These processes replicate the natural diamond formation process, creating genuine diamonds that IGI then certifies.
