Why Diamond Certifications Matter

• Quality Verification
  Certifications by reputable labs offer an unbiased, third-party assessment of a diamond’s 4Cs (Carat, Colour, Clarity and Cut)
  – Carat, referring to the exact weight of the diamond, measured in carats (ct) and points (pt). A single carat is equal to 100 points.
  – Colour, referring to how colourless a diamond is. Standardized colour scale ranges from D (colourless) to Z (light yellow). The colour grade of a diamond has a significant impact on its beauty and value.
  – Clarity, referring to the presence or absence of internal flaws (inclusions) and external blemishes on the surface of a diamond. These imperfections can affect the way light travels through the diamond, impacting its brilliance and fire (colourful flashes of light).
  – Cut, arguably the most important of the 4Cs, has a direct impact on a diamond’s brilliance, fire and scintillation. A well-cut diamond will sparkle magnificently, reflecting light back through the crown and emitting a dazzling display of fire.
• Accurate Pricing
  Fair, market-based pricing is essential for businesses that trade, manufacture, or invest in diamonds. As characteristics like colour and clarity grades directly impact market value, diamond certifications inform and fix pricing. These certifications help take the guesswork out of the picture. Fair, market-based pricing is essential for businesses that trade, manufacture, or invest in diamonds. And this is where the certifications help build trust between the buyers and sellers, ensuring everyone involved in the transaction is confident that the diamond is priced accurately.
• Transparency
  Certifications foster transparency and confidence, providing businesses and consumers with transparency throughout the supply chain. They often indicate a diamond’s origin, and sometimes include information about its cutting and polishing process. This provides buyers with a clear picture of the diamond’s history.
• Investment Confidence
  Stones with certificates from top-tier labs like GIA tend to retain their value better over time, making them more secure investments. The reputation and consistency of these labs give investors’ confidence that their diamonds are accurately represented, and their value will be recognized in the future.
