Their expertise ensures consistent, transparent reporting for CVD and HPHT-grown stones. b. Detailed Report Format: IGI’s certificate provides a comprehensive diagram, exact proportions, fluorescence intensity, and polishing/graining details—ideal for professional jewelers. c. Competitive Pricing: As IGI focuses heavily on cultivated stones, their grading fees are often lower, making IGI-certified diamonds more accessible for budget-conscious shoppers. d.

Security Features: GIA certificates include tamper-proof measures, unique report numbers, and online verification—a significant trust booster. d. Global Resale & Insurance Acceptance: Due to its prestige, GIA-certified diamonds often fetch higher resale value and smoother insurance appraisals.
