Beyond the Certificate

Beyond the Certificate

At AG & CO Jewellery, we believe that a diamond’s true beauty cannot be captured by a certificate alone. While grading reports from GIA, IGI, and other reputable institutions provide valuable insights, they do not tell the full story of a diamond’s brilliance. That’s why we go beyond the certificate, meticulously handpicking each diamond to meet our exceptional standards of quality, beauty, and value.

The AG & CO Difference

A diamond’s GIA or IGI certificate provides details about its cut, color, clarity, and carat weight, but it does not reveal how the diamond will look in person. Some diamonds may have excellent technical grades yet appear dull, hazy, or lifeless. We go deeper—screening each diamond for the most important visual and structural qualities that impact its brilliance.

Our Diamond Screening Process

  • Luster & Light Performance: We examine how each diamond interacts with light, ensuring exceptional fire, brilliance, and scintillation.
  • Eye-Cleanliness & Inclusions: Only diamonds that are truly eye-clean, without visible inclusions, pass our selection.
  • BGM (Brown, Green, Milky Undertones): Every diamond is inspected under multiple lighting conditions to ensure pure, vibrant color.
  • Fluorescence Impact: We avoid diamonds with fluorescence that negatively affects transparency.
  • Symmetry & Proportions: Our diamonds are selected based on precision-cut proportions for superior light reflection.
