Diamond Certification

Lab-Grown Diamond CertificationĀ (commonly from IGI, EGL, SGL, GIA, and Ouros Authentic Certificate) is a physical and electronic document you receive from reputable third-party labs that describe a diamondā€™s characteristics.
Diamond certificationĀ serves as proof that your purchased diamond has passed all the stringent standards set by authoritative laboratories like GIA and IGI.

What is a Certified Diamond?

When purchasing a diamond, ensuring its authenticity is crucial to avoid being deceived by the seller. A certified diamond comes with a seal of approval from trustworthy third-party labs. The certification report includes comprehensive details about the diamondā€™s 4Cs (Cut, Color, Clarity, Carat), symmetry, dimensions, and fluorescence. Therefore, always opt for certified diamonds for your engagement rings and wedding accessories.
For instance, SGL certified diamonds provide precise information about the 4Cs with exact proportions. There is no need for additional verification as SGLā€™s experienced quality inspectors meticulously check each diamond. If you prefer SGL certified diamonds, we can provide them at Zelsu Jewels.
