At Victoria Changs, our commitment to excellence begins with the gemstones we offer. Every diamond and gemstone in our collection is ethically sourced and meticulously selected. To ensure you receive nothing but the best, we proudly feature stones certified by the Gemological Institute of America (GIA)—the world’s most trusted authority in diamond and gemstone grading.

What is GIA?
The Gemological Institute of America (GIA) is a non-profit organization and the global leader in gemological research, education, and grading. Founded in 1931, GIA developed the universally accepted 4Cs of Diamond Quality—Cut, Color, Clarity, and Carat Weight—and established the grading standards that define the industry today.

Why GIA Certification Matters
A GIA certificate is more than just a document—it's a guarantee of quality and authenticity. When you purchase a GIA-certified diamond or gemstone from Victoria Changs, you receive:

  • Unbiased Grading: GIA is a third-party institution with no stake in the sale of gemstones, ensuring complete objectivity.
  • Detailed Analysis: Each certificate provides a comprehensive breakdown of the stone’s attributes, including a plotted diagram of clarity characteristics.
  • Global Recognition: GIA is the most respected certification authority worldwide, adding long-term value and assurance to your purchase.
  • Advanced Technology: GIA uses cutting-edge scientific instruments to evaluate stones with precision and consistency.

What’s Included in a GIA Certificate?
Each GIA certificate typically includes:

  • 4Cs Grading (Cut, Color, Clarity, Carat Weight)
  • Measurements and Proportions
  • Polish and Symmetry Ratings
  • Fluorescence Details
  • Laser Inscription (if applicable)
