Certificate of Authority
EVERYTHING you need to know about your jewellery piece.
What is the carat weight of your diamond earrings, what is the history of their origin, what are the stone proportions, what are the stone clarity characteristics? All these answers can be found in the certificate of authority of your jewellery piece.
The certificate of authority is the product passport, which contains all the information about the piece. It is issued after an independent gemological examination for each individual piece of jewellery. The document guarantees the authenticity of the jewellery and proves that its characteristics meet the current quality standards. For these purposes, the document is assigned with an individual report number, a QR code and a hologram seal.
The certificate of authority contains detailed information about the piece (style, measurements, material, grading information).
