When shopping for a diamond, ensuring its quality and authenticity is crucial. Two of the most respected gemological institutes offering diamond certification are the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). Both provide independent assessments using a standardized system, but they have some key differences to consider.

  • IGI: Founded in 1975, IGI is a reputable lab with a global presence. While their standards are improving, they may be slightly less strict than GIA’s, potentially affecting resale value. However lab diamonds, IGI can be a good choice for diamonds graded higher in cut, which can influence brilliance.

Price and Services:

  • GIA: GIA certification typically costs more due to their rigorous process and prestige.

  • IGI: IGI certification is often more affordable, making it an attractive option for budget-conscious buyers. Additionally, IGI certifies loose diamonds and mounted jewelry, whereas GIA focuses solely on loose stones.

Choosing the Right Certification:

  • Priority: Resale Value: Opt for GIA certification for maximum resale value and industry-trusted grading.

  • Priority: Cut and Affordability: Consider IGI if a well-cut diamond is a priority and you’re on a budget.
