IGI, GIA and HRD certificates
Certificates help you compare quality, but the right choice also depends on proportion, budget and design.
A diamond certificate is an independent description of a stone. It records details including carat, colour, clarity, shape and measurements, and sometimes comments on fluorescence or polish.
What a certificate does
It provides a reference. You can compare stones using a shared language and check whether their origin and specifications are correct. IGI is widely used for lab-grown diamonds; GIA is often the international reference for natural diamonds.
What a certificate does not do
A certificate does not fully describe how a diamond feels in a ring. Two stones with similar grades can look different because of their proportions, facet pattern, inclusion placement and the chosen setting.
How DYOTA reads a certificate
DYOTA checks whether the certificate is consistent with the price and intended use. We then assess the stone visually: colour, fire, proportions, inclusions and suitability for the design.
