IGI-Certified vs GIA-Certified Diamonds: What You Should Know 💎

IGI-Certified vs GIA-Certified Diamonds: What You Should Know 💎

📝 What Is a Diamond Certification?

A diamond certification (also called a grading report) is an independent document that details the diamond’s most important characteristics:

  • Carat, Cut, Colour, Clarity (the “4Cs”)
  • Analyses of symmetry, polish, fluorescence, and shape
  • Laser-inscribed ID number on the ‘girdle’ of the diamond for traceability

These certificates provide reliable, unbiased evidence of a diamond’s quality and origin which critical for both your confidence and insurance requirements.

💼 GIA: The Traditional Gold Standard

GIA (Gemological Institute of America)

GIA has been setting the benchmark since 1931. Known for its consistency and strict grading process, GIA is often the go-to for natural diamonds.

  • Highly consistent and strict, the scores demand precision
  • Uses anonymous grading, cross-checks by multiple gemologists.
  • Laser inscription ensures the diamond matches the certificate every time.
  • Recognised worldwide and favours resale value

Ideal for mined diamonds but lenient with lab-grown, and the process takes longer and commands a higher fee.

💬 Expert Tip from the MJS Team

Don’t choose a diamond just for the certificate. Look at the quality of the stone itself, how it sparkles, how it performs, and how it makes you feel.

A beautiful diamond, IGI or GIA certified, should still be chosen with your heart (and a little help from our gem experts).
