A Quality Certificate for a jewel is a document that legitimizes the authenticity of all the components and materials contained in a Fine Jewelery piece, and in which each and every one of their features are accuratedly detailed (weight and gold alloy, the 4c of the Diamond, etc).

Each and every one of the pieces of our brand are accompanied by their corresponding Quality Certificate.

  • For jewels that contain diamonds greater than 0.35 ct., GODIAM accompanies its Quality Certificate of the piece with an International GIA|HRD|IGI Certificate.
  • All jewels that contain diamonds up to 0.35 cts, our firm issues its own Quality Certificate.
